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

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
