Build instructions for Hadoop
----------------------------------------------------------------------------------
Requirements:
* Unix System
* JDK 1.8
* Maven 3.3 or later
* Boost 1.72 (if compiling native code)
* Protocol Buffers 3.7.1 (if compiling native code)
* CMake 3.19 or newer (if compiling native code)
* Zlib devel (if compiling native code)
* Cyrus SASL devel (if compiling native code)
* One of the compilers that support thread_local storage: GCC 9.3.0 or later, Visual Studio,
Clang (community version), Clang (version for iOS 9 and later) (if compiling native code)
* openssl devel (if compiling native hadoop-pipes and to get the best HDFS encryption performance)
* Linux FUSE (Filesystem in Userspace) version 2.6 or above (if compiling fuse_dfs)
* Doxygen ( if compiling libhdfspp and generating the documents )
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
* python (for releasedocs)
* bats (for shell code testing)
* Node.js / bower / Ember-cli (for YARN UI v2 building)
----------------------------------------------------------------------------------
The easiest way to get an environment with all the appropriate tools is by means
of the provided Docker config.
This requires a recent version of docker (1.4.1 and higher are known to work).
On Linux / Mac:
Install Docker and run this command:
$ ./start-build-env.sh
The prompt which is then presented is located at a mounted version of the source tree
and all required tools for testing and building have been installed and configured.
Note that from within this docker environment you ONLY have access to the Hadoop source
tree from where you started. So if you need to run
dev-support/bin/test-patch /path/to/my.patch
then the patch must be placed inside the hadoop source tree.
Known issues:
- On Mac with Boot2Docker the performance on the mounted directory is currently extremely slow.
This is a known problem related to boot2docker on the Mac.
See:
https://github.com/boot2docker/boot2docker/issues/593
This issue has been resolved as a duplicate, and they point to a new feature for utilizing NFS mounts
as the proposed solution:
https://github.com/boot2docker/boot2docker/issues/64
An alternative solution to this problem is to install Linux native inside a virtual machine
and run your IDE and Docker etc inside that VM.

----------------------------------------------------------------------------------
Where to run Maven from?
It can be run from any module. The only catch is that if not run from trunk
all modules that are not part of the build run must be installed in the local
Maven cache or available in a Maven repository.
----------------------------------------------------------------------------------
Maven build goals:
* Clean : mvn clean [-Preleasedocs]
* Compile : mvn compile [-Pnative]
* Run tests : mvn test [-Pnative] [-Pshelltest]
* Create JAR : mvn package
* Run spotbugs : mvn compile spotbugs:spotbugs
* Run checkstyle : mvn compile checkstyle:checkstyle
* Install JAR in M2 cache : mvn install
* Deploy JAR to Maven repo : mvn deploy
* Run clover : mvn test -Pclover
* Run Rat : mvn apache-rat:check
* Build javadocs : mvn javadoc:javadoc
* Build distribution : mvn package [-Pdist][-Pdocs][-Psrc][-Pnative][-Dtar][-Preleasedocs][-Pyarn-ui]
* Change Hadoop version : mvn versions:set -DnewVersion=NEWVERSION
Build options:
* Use -Pnative to compile/bundle native code
* Use -Pdocs to generate & bundle the documentation in the distribution (using -Pdist)
* Use -Psrc to create a project source TAR.GZ
* Use -Dtar to create a TAR with the distribution (using -Pdist)
* Use -Preleasedocs to include the changelog and release docs (requires Internet connectivity)
* Use -Pyarn-ui to build YARN UI v2. (Requires Internet connectivity)
* Use -DskipShade to disable client jar shading to speed up build times (in
development environments only, not to build release artifacts)
YARN Application Timeline Service V2 build options:
YARN Timeline Service v.2 chooses Apache HBase as the primary backing storage. The supported
versions of Apache HBase are 1.7.1 (default) and 2.2.4.
* HBase 1.7.1 is used by default to build Hadoop. The official releases are ready to use if you
plan on running Timeline Service v2 with HBase 1.7.1.
* Use -Dhbase.profile=2.0 to build Hadoop with HBase 2.2.4. Provide this option if you plan
on running Timeline Service v2 with HBase 2.x.
Snappy build options:
Snappy is a compression library that can be utilized by the native code.
It is currently an optional component, meaning that Hadoop can be built with
or without this dependency. Snappy library as optional dependency is only
used for hadoop-mapreduce-client-nativetask.
* Use -Drequire.snappy to fail the build if libsnappy.so is not found.
If this option is not specified and the snappy library is missing,
we silently build a version of libhadoop.so that cannot make use of snappy.
This option is recommended if you plan on making use of snappy and want
to get more repeatable builds.
* Use -Dsnappy.prefix to specify a nonstandard location for the libsnappy
header files and library files. You do not need this option if you have
installed snappy using a package manager.
* Use -Dsnappy.lib to specify a nonstandard location for the libsnappy library
files. Similarly to snappy.prefix, you do not need this option if you have
installed snappy using a package manager.
* Use -Dbundle.snappy to copy the contents of the snappy.lib directory into
the final tar file. This option requires that -Dsnappy.lib is also given,
and it ignores the -Dsnappy.prefix option. If -Dsnappy.lib isn't given, the
bundling and building will fail.
ZStandard build options:
ZStandard is a compression library that can be utilized by the native code.
It is currently an optional component, meaning that Hadoop can be built with
or without this dependency.
* Use -Drequire.zstd to fail the build if libzstd.so is not found.
If this option is not specified and the zstd library is missing.
* Use -Dzstd.prefix to specify a nonstandard location for the libzstd
header files and library files. You do not need this option if you have
installed zstandard using a package manager.
* Use -Dzstd.lib to specify a nonstandard location for the libzstd library
files. Similarly to zstd.prefix, you do not need this option if you have
installed using a package manager.
* Use -Dbundle.zstd to copy the contents of the zstd.lib directory into
the final tar file. This option requires that -Dzstd.lib is also given,
and it ignores the -Dzstd.prefix option. If -Dzstd.lib isn't given, the
bundling and building will fail.
OpenSSL build options:
OpenSSL includes a crypto library that can be utilized by the native code.
It is currently an optional component, meaning that Hadoop can be built with
or without this dependency.
* Use -Drequire.openssl to fail the build if libcrypto.so is not found.
If this option is not specified and the openssl library is missing,
we silently build a version of libhadoop.so that cannot make use of
openssl. This option is recommended if you plan on making use of openssl
and want to get more repeatable builds.
* Use -Dopenssl.prefix to specify a nonstandard location for the libcrypto
header files and library files. You do not need this option if you have
installed openssl using a package manager.
* Use -Dopenssl.lib to specify a nonstandard location for the libcrypto library
files. Similarly to openssl.prefix, you do not need this option if you have
installed openssl using a package manager.
* Use -Dbundle.openssl to copy the contents of the openssl.lib directory into
the final tar file. This option requires that -Dopenssl.lib is also given,
and it ignores the -Dopenssl.prefix option. If -Dopenssl.lib isn't given, the
bundling and building will fail.
Tests options:
* Use -DskipTests to skip tests when running the following Maven goals:
'package', 'install', 'deploy' or 'verify'
* -Dtest=<TESTCLASSNAME>,<TESTCLASSNAME#METHODNAME>,....
* -Dtest.exclude=<TESTCLASSNAME>
* -Dtest.exclude.pattern=**/<TESTCLASSNAME1>.java,**/<TESTCLASSNAME2>.java
* To run all native unit tests, use: mvn test -Pnative -Dtest=allNative
* To run a specific native unit test, use: mvn test -Pnative -Dtest=<test>
For example, to run test_bulk_crc32, you would use:
mvn test -Pnative -Dtest=test_bulk_crc32
Intel ISA-L build options:
Intel ISA-L is an erasure coding library that can be utilized by the native code.
It is currently an optional component, meaning that Hadoop can be built with
or without this dependency. Note the library is used via dynamic module. Please
reference the official site for the library details.
https://01.org/intel%C2%AE-storage-acceleration-library-open-source-version
(OR https://github.com/01org/isa-l)
* Use -Drequire.isal to fail the build if libisal.so is not found.
If this option is not specified and the isal library is missing,
we silently build a version of libhadoop.so that cannot make use of ISA-L and
the native raw erasure coders.
This option is recommended if you plan on making use of native raw erasure
coders and want to get more repeatable builds.
* Use -Disal.prefix to specify a nonstandard location for the libisal
library files. You do not need this option if you have installed ISA-L to the
system library path.
* Use -Disal.lib to specify a nonstandard location for the libisal library
files.
* Use -Dbundle.isal to copy the contents of the isal.lib directory into
the final tar file. This option requires that -Disal.lib is also given,
and it ignores the -Disal.prefix option. If -Disal.lib isn't given, the
bundling and building will fail.
Special plugins: OWASP's dependency-check:
OWASP's dependency-check plugin will scan the third party dependencies
of this project for known CVEs (security vulnerabilities against them).
It will produce a report in target/dependency-check-report.html. To
invoke, run 'mvn dependency-check:aggregate'. Note that this plugin
requires maven 3.1.1 or greater.
PMDK library build options:
The Persistent Memory Development Kit (PMDK), formerly known as NVML, is a growing
collection of libraries which have been developed for various use cases, tuned,
validated to production quality, and thoroughly documented. These libraries are built
on the Direct Access (DAX) feature available in both Linux and Windows, which allows
applications directly load/store access to persistent memory by memory-mapping files
on a persistent memory aware file system.
It is currently an optional component, meaning that Hadoop can be built without
this dependency. Please Note the library is used via dynamic module. For getting
more details please refer to the official sites:
http://pmem.io/ and https://github.com/pmem/pmdk.
* -Drequire.pmdk is used to build the project with PMDK libraries forcibly. With this
option provided, the build will fail if libpmem library is not found. If this option
is not given, the build will generate a version of Hadoop with libhadoop.so.
And storage class memory(SCM) backed HDFS cache is still supported without PMDK involved.
Because PMDK can bring better caching write/read performance, it is recommended to build
the project with this option if user plans to use SCM backed HDFS cache.
* -Dpmdk.lib is used to specify a nonstandard location for PMDK libraries if they are not
under /usr/lib or /usr/lib64.
* -Dbundle.pmdk is used to copy the specified libpmem libraries into the distribution tar
package. This option requires that -Dpmdk.lib is specified. With -Dbundle.pmdk provided,
the build will fail if -Dpmdk.lib is not specified.
Controlling the redistribution of the protobuf-2.5 dependency
The protobuf 2.5.0 library is used at compile time to compile the class
org.apache.hadoop.ipc.ProtobufHelper; this class known to have been used by
external projects in the past. Protobuf 2.5 is not used elsewhere in
the Hadoop codebase; alongside the move to Protobuf 3.x a private successor
class, org.apache.hadoop.ipc.internal.ShadedProtobufHelper is now used.
The hadoop-common JAR still declares a dependency on protobuf-2.5, but this
is likely to change in the future. The maven scope of the dependency can be
set with the common.protobuf2.scope option.
It can be set to "provided" in a build:
-Dcommon.protobuf2.scope=provided
If this is done then protobuf-2.5.0.jar will no longer be exported as a dependency,
and will then be omitted from the share/hadoop/common/lib/ directory of
any Hadoop distribution built. Any application declaring a dependency on hadoop-commmon
will no longer get the dependency; if they need it then they must explicitly declare it:
<dependency>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-java</artifactId>
<version>2.5.0</version>
</dependency>
----------------------------------------------------------------------------------
Building components separately
If you are building a submodule directory, all the hadoop dependencies this
submodule has will be resolved as all other 3rd party dependencies. This is,
from the Maven cache or from a Maven repository (if not available in the cache
or the SNAPSHOT 'timed out').
An alternative is to run 'mvn install -DskipTests' from Hadoop source top
level once; and then work from the submodule. Keep in mind that SNAPSHOTs
time out after a while, using the Maven '-nsu' will stop Maven from trying
to update SNAPSHOTs from external repos.
----------------------------------------------------------------------------------
Importing projects to eclipse
At first, install artifacts including hadoop-maven-plugins at the top of the source tree.
$ mvn clean install -DskipTests -DskipShade
Then, import to eclipse by specifying the root directory of the project via
[File] > [Import] > [Maven] > [Existing Maven Projects].
----------------------------------------------------------------------------------
Building distributions:
Create binary distribution without native code and without Javadocs:
$ mvn package -Pdist -DskipTests -Dtar -Dmaven.javadoc.skip=true
Create binary distribution with native code:
$ mvn package -Pdist,native -DskipTests -Dtar
Create source distribution:
$ mvn package -Psrc -DskipTests
Create source and binary distributions with native code:
$ mvn package -Pdist,native,src -DskipTests -Dtar
Create a local staging version of the website (in /tmp/hadoop-site)
$ mvn site site:stage -Preleasedocs,docs -DstagingDirectory=/tmp/hadoop-site
Note that the site needs to be built in a second pass after other artifacts.
----------------------------------------------------------------------------------
Installing Hadoop
Look for these HTML files after you build the document by the above commands.
* Single Node Setup:
hadoop-project-dist/hadoop-common/SingleCluster.html
* Cluster Setup:
hadoop-project-dist/hadoop-common/ClusterSetup.html
----------------------------------------------------------------------------------
Handling out of memory errors in builds
----------------------------------------------------------------------------------
If the build process fails with an out of memory error, you should be able to fix
it by increasing the memory used by maven which can be done via the environment
variable MAVEN_OPTS.
Here is an example setting to allocate between 256 MB and 1.5 GB of heap space to
Maven
export MAVEN_OPTS="-Xms256m -Xmx1536m"
----------------------------------------------------------------------------------
Building on macOS (without Docker)
----------------------------------------------------------------------------------
Installing required dependencies for clean install of macOS 10.14:
* Install Xcode Command Line Tools
$ xcode-select --install
* Install Homebrew
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
* Install OpenJDK 8
$ brew tap AdoptOpenJDK/openjdk
$ brew cask install adoptopenjdk8
* Install maven and tools
$ brew install maven autoconf automake cmake wget
* Install native libraries, only openssl is required to compile native code,
you may optionally install zlib, lz4, etc.
$ brew install openssl
* Protocol Buffers 3.7.1 (required to compile native code)
$ wget https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/protobuf-java-3.7.1.tar.gz
$ mkdir -p protobuf-3.7 && tar zxvf protobuf-java-3.7.1.tar.gz --strip-components 1 -C protobuf-3.7
$ cd protobuf-3.7
$ ./configure
$ make
$ make check
$ make install
$ protoc --version
Note that building Hadoop 3.1.1/3.1.2/3.2.0 native code from source is broken
on macOS. For 3.1.1/3.1.2, you need to manually backport YARN-8622. For 3.2.0,
you need to backport both YARN-8622 and YARN-9487 in order to build native code.
----------------------------------------------------------------------------------
Building command example:
* Create binary distribution with native code but without documentation:
$ mvn package -Pdist,native -DskipTests -Dmaven.javadoc.skip \
-Dopenssl.prefix=/usr/local/opt/openssl
Note that the command above manually specified the openssl library and include
path. This is necessary at least for Homebrewed OpenSSL.
----------------------------------------------------------------------------------

Building on Windows 10
----------------------------------------------------------------------------------
Requirements:
* Windows 10
* JDK 1.8
* Maven 3.0 or later (maven.apache.org)
* Boost 1.72 (boost.org)
* Protocol Buffers 3.7.1 (https://github.com/protocolbuffers/protobuf/releases)
* CMake 3.19 or newer (cmake.org)
* Visual Studio 2019 (visualstudio.com)
* Windows SDK 8.1 (optional, if building CPU rate control for the container executor. Get this from
http://msdn.microsoft.com/en-us/windows/bg162891.aspx)
* Zlib (zlib.net, if building native code bindings for zlib)
* Git (preferably, get this from https://git-scm.com/download/win since the package also contains
Unix command-line tools that are needed during packaging).
* Python (python.org, for generation of docs using 'mvn site')
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
----------------------------------------------------------------------------------
Building guidelines:
Hadoop repository provides the Dockerfile for building Hadoop on Windows 10, located at
dev-support/docker/Dockerfile_windows_10. It is highly recommended to use this and create the
Docker image for building Hadoop on Windows 10, since you don't have to install anything else
other than Docker and no additional steps are required in terms of aligning the environment with
the necessary paths etc.
However, if you still prefer taking the route of not using Docker, this Dockerfile_windows_10 will
still be immensely useful as a raw guide for all the steps involved in creating the environment
needed to build Hadoop on Windows 10.
Building using the Docker:
We first need to build the Docker image for building Hadoop on Windows 10. Run this command from
the root of the Hadoop repository.
> docker build -t hadoop-windows-10-builder -f .\dev-support\docker\Dockerfile_windows_10 .\dev-support\docker\
Start the container with the image that we just built.
> docker run --rm -it hadoop-windows-10-builder
You can now clone the Hadoop repo inside this container and proceed with the build.
NOTE:
While one may perceive the idea of mounting the locally cloned (on the host filesystem) Hadoop
repository into the container (using the -v option), we have seen the build to fail owing to some
files not being able to be located by Maven. Thus, we suggest cloning the Hadoop repository to a
non-mounted folder inside the container and proceed with the build. When the build is completed,
you may use the "docker cp" command to copy the built Hadoop tar.gz file from the docker container
to the host filesystem. If you still would like to mount the Hadoop codebase, a workaround would
be to copy the mounted Hadoop codebase into another folder (which doesn't point to a mount) in the
container's filesystem and use this for building.
However, we noticed no build issues when the Maven repository from the host filesystem was mounted
into the container. One may use this to greatly reduce the build time. Assuming that the Maven
repository is located at D:\Maven\Repository in the host filesystem, one can use the following
command to mount the same onto the default Maven repository location while launching the container.
> docker run --rm -v D:\Maven\Repository:C:\Users\ContainerAdministrator\.m2\repository -it hadoop-windows-10-builder
Building:
Keep the source code tree in a short path to avoid running into problems related
to Windows maximum path length limitation (for example, C:\hdc).
There is one support command file located in dev-support called win-paths-eg.cmd.
It should be copied somewhere convenient and modified to fit your needs.
win-paths-eg.cmd sets up the environment for use. You will need to modify this
file. It will put all of the required components in the command path,
configure the bit-ness of the build, and set several optional components.
Several tests require that the user must have the Create Symbolic Links
privilege.
To simplify the installation of Boost, Protocol buffers, OpenSSL and Zlib dependencies we can use
vcpkg (https://github.com/Microsoft/vcpkg.git). Upon cloning the vcpkg repo, checkout the commit
7ffa425e1db8b0c3edf9c50f2f3a0f25a324541d to get the required versions of the dependencies
mentioned above.
> git clone https://github.com/Microsoft/vcpkg.git
> cd vcpkg
> git checkout 7ffa425e1db8b0c3edf9c50f2f3a0f25a324541d
> .\bootstrap-vcpkg.bat
> .\vcpkg.exe install boost:x64-windows
> .\vcpkg.exe install protobuf:x64-windows
> .\vcpkg.exe install openssl:x64-windows
> .\vcpkg.exe install zlib:x64-windows
Set the following environment variables -
(Assuming that vcpkg was checked out at C:\vcpkg)
> set PROTOBUF_HOME=C:\vcpkg\installed\x64-windows
> set MAVEN_OPTS=-Xmx2048M -Xss128M
All Maven goals are the same as described above with the exception that
native code is built by enabling the 'native-win' Maven profile. -Pnative-win
is enabled by default when building on Windows since the native components
are required (not optional) on Windows.
If native code bindings for zlib are required, then the zlib headers must be
deployed on the build machine. Set the ZLIB_HOME environment variable to the
directory containing the headers.
set ZLIB_HOME=C:\zlib-1.2.7
At runtime, zlib1.dll must be accessible on the PATH. Hadoop has been tested
with zlib 1.2.7, built using Visual Studio 2010 out of contrib\vstudio\vc10 in
the zlib 1.2.7 source tree.
http://www.zlib.net/
Build command:
The following command builds all the modules in the Hadoop project and generates the tar.gz file in
hadoop-dist/target upon successful build. Run these commands from an
"x64 Native Tools Command Prompt for VS 2019" which can be found under "Visual Studio 2019" in the
Windows start menu. If you're using the Docker image from Dockerfile_windows_10, you'll be
logged into "x64 Native Tools Command Prompt for VS 2019" automatically when you start the

Running compatibility checks with checkcompatibility.py
Invoke `./dev-support/bin/checkcompatibility.py` to run Java API Compliance Checker
to compare the public Java APIs of two git objects. This can be used by release
managers to compare the compatibility of a previous and current release.
As an example, this invocation will check the compatibility of interfaces annotated as Public or LimitedPrivate:
./dev-support/bin/checkcompatibility.py --annotation org.apache.hadoop.classification.InterfaceAudience.Public --annotation org.apache.hadoop.classification.InterfaceAudience.LimitedPrivate --include "hadoop.*" branch-2.7.2 trunk
----------------------------------------------------------------------------------
Changing the Hadoop version declared returned by VersionInfo
If for compatibility reasons the version of Hadoop has to be declared as a 2.x release in the information returned by
org.apache.hadoop.util.VersionInfo, set the property declared.hadoop.version to the desired version.
For example: mvn package -Pdist -Ddeclared.hadoop.version=2.11
If unset, the project version declared in the POM file is used.
