Build instructions for Hadoop
|
|
|
|
----------------------------------------------------------------------------------
|
|
Requirements:
|
|
|
|
* Unix System
|
|
* JDK 1.6
|
|
* Maven 3.0
|
|
* Findbugs 1.3.9 (if running findbugs)
|
|
* ProtocolBuffer 2.4.1+ (for MapReduce and HDFS)
|
|
* CMake 2.6 or newer (if compiling native code)
|
|
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
|
|
|
|
----------------------------------------------------------------------------------
|
|
Maven main modules:
|
|
|
|
hadoop (Main Hadoop project)
|
|
- hadoop-project (Parent POM for all Hadoop Maven modules. )
|
|
(All plugins & dependencies versions are defined here.)
|
|
- hadoop-project-dist (Parent POM for modules that generate distributions.)
|
|
- hadoop-annotations (Generates the Hadoop doclet used to generated the Javadocs)
|
|
- hadoop-assemblies (Maven assemblies used by the different modules)
|
|
- hadoop-common-project (Hadoop Common)
|
|
- hadoop-hdfs-project (Hadoop HDFS)
|
|
- hadoop-mapreduce-project (Hadoop MapReduce)
|
|
- hadoop-tools (Hadoop tools like Streaming, Distcp, etc.)
|
|
- hadoop-dist (Hadoop distribution assembler)
|
|
|
|
----------------------------------------------------------------------------------
|
|
Where to run Maven from?
|
|
|
|
It can be run from any module. The only catch is that if not run from utrunk
|
|
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
|
|
* Compile : mvn compile [-Pnative]
|
|
* Run tests : mvn test [-Pnative]
|
|
* Create JAR : mvn package
|
|
* Run findbugs : mvn compile findbugs:findbugs
|
|
* 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 [-DcloverLicenseLocation=${user.name}/.clover.license]
|
|
* Run Rat : mvn apache-rat:check
|
|
* Build javadocs : mvn javadoc:javadoc
|
|
* Build distribution : mvn package [-Pdist][-Pdocs][-Psrc][-Pnative][-Dtar]
|
|
* 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)
|
|
|
|
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.
|
|
|
|
* 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.
|
|
|
|
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

Building distributions:
|
|
|
|
Create binary distribution without native code and without documentation:
|
|
|
|
$ mvn package -Pdist -DskipTests -Dtar
|
|
|
|
Create binary distribution with native code and with documentation:
|
|
|
|
$ mvn package -Pdist,native,docs -DskipTests -Dtar
|
|
|
|
Create source distribution:
|
|
|
|
$ mvn package -Psrc -DskipTests
|
|
|
|
Create source and binary distributions with native code and documentation:
|
|
|
|
$ mvn package -Pdist,native,docs,src -DskipTests -Dtar
|
|
|
|
Create a local staging version of the website (in /tmp/hadoop-site)
|
|
|
|
$ mvn clean site; mvn site:stage -DstagingDirectory=/tmp/hadoop-site
|
|
|
