-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
