YARN (YET ANOTHER RESOURCE NEGOTIATOR or YARN Application Resource Negotiator)
|
||||
------------------------------------------------------------------------------
|
||||
|
||||
Requirements
|
||||
-------------
|
||||
Java: JDK 1.6
|
||||
Maven: Maven 3
|
||||
|
||||
Setup
|
||||
-----
|
||||
Install protobuf 2.5.0 (Download from http://code.google.com/p/protobuf/downloads/list)
|
||||
- install the protoc executable (configure, make, make install)
|
||||
- install the maven artifact (cd java; mvn install)
|
||||
|
||||
|
||||
Quick Maven Tips
|
||||
----------------
|
||||
clean workspace: mvn clean
|
||||
compile and test: mvn install
|
||||
skip tests: mvn install -DskipTests
|
||||
skip test execution but compile: mvn install -Dmaven.test.skip.exec=true
|
||||
clean and test: mvn clean install
|
||||
run selected test after compile: mvn test -Dtest=TestClassName (combined: mvn clean install -Dtest=TestClassName)
|
||||
create runnable binaries after install: mvn assembly:assembly -Pnative (combined: mvn clean install assembly:assembly -Pnative)
|
||||
|
||||
Eclipse Projects
|
||||
----------------
|
||||
http://maven.apache.org/guides/mini/guide-ide-eclipse.html
|
||||
|
||||
1. Generate .project and .classpath files in all maven modules
|
||||
mvn eclipse:eclipse
|
||||
CAUTION: If the project structure has changed from your previous workspace, clean up all .project and .classpath files recursively. Then run:
|
||||
mvn eclipse:eclipse
|
||||
|
||||
2. Import the projects in eclipse.
|
||||
|
||||
3. Set the environment variable M2_REPO to point to your .m2/repository location.
|
||||
|
||||
NetBeans Projects
|
||||
-----------------
|
||||
|
||||
NetBeans has builtin support of maven projects. Just "Open Project..."
|
||||
and everything is setup automatically. Verified with NetBeans 6.9.1.
|
||||
|
||||
|
||||
Custom Hadoop Dependencies
|
||||
--------------------------
|
||||
|
||||
By default Hadoop dependencies are specified in the top-level pom.xml
|
||||
properties section. One can override them via -Dhadoop-common.version=...
|
||||
on the command line. ~/.m2/settings.xml can also be used to specify
|
||||
these properties in different profiles, which is useful for IDEs.
|
||||
|
||||
Modules
|
||||
-------
|
||||
YARN consists of multiple modules. The modules are listed below as per the directory structure:
|
||||
|
||||
hadoop-yarn-api - YARN's cross platform external interface
|
||||
|
||||
hadoop-yarn-common - Utilities which can be used by yarn clients and server
|
||||
|
||||
hadoop-yarn-server - Implementation of the hadoop-yarn-api
|
||||
hadoop-yarn-server-common - APIs shared between resourcemanager and nodemanager
|
||||
hadoop-yarn-server-nodemanager (TaskTracker replacement)
|
||||
hadoop-yarn-server-resourcemanager (JobTracker replacement)
|
||||
|
||||
Utilities for understanding the code
|
||||
------------------------------------
|
||||
Almost all of the yarn components as well as the mapreduce framework use
|
||||
state-machines for all the data objects. To understand those central pieces of
|
||||
the code, a visual representation of the state-machines helps much. You can first
|
||||
convert the state-machines into graphviz(.gv) format by
|
||||
running:
|
||||
mvn compile -Pvisualize
|
||||
Then you can use the dot program for generating directed graphs and convert the above
|
||||
.gv files to images. The graphviz package has the needed dot program and related
|
||||
utilites.For e.g., to generate png files you can run:
|
||||
dot -Tpng NodeManager.gv > NodeManager.png
