Date Tue, 18 Jun 2013 05:20:19 GMT
Hi Rahul,

                You can make use of the below configuration to set up the launch context for
your application master.

  <!-- Applications' Configuration-->

  <property>
    <description>CLASSPATH for YARN applications. A comma-separated list
    of CLASSPATH entries</description>
     <name>yarn.application.classpath</name>
     <value>$HADOOP_CONF_DIR,$HADOOP_COMMON_HOME/share/hadoop/common/*,$HADOOP_COMMON_HOME/share/hadoop/common/lib/*,$HADOOP_HDFS_HOME/share/hadoop/hdfs/*,$HADOOP_HDFS_HOME/share/hadoop/hdfs/lib/*,$HADOOP_YARN_HOME/share/hadoop/yarn/*,$HADOOP_YARN_HOME/share/hadoop/yarn/lib/*</value>
  </property>

Thanks
Devaraj K

Subject: Environment variable representing classpath for AM launch

Hi,
Is ther's any environment variable (available in all nodes of an Yarn cluster) which represents
a java classpath containing all the core jars of yarn. I was thinking to use that variable
to setup the environment where to run the application master.
Thanks,
Rahul
