------------------------------------

             Summary: add an env variable for the YARN AM classpath
                 Key: YARN-1554
                 URL: https://issues.apache.org/jira/browse/YARN-1554
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 2.2.0
            Reporter: Steve Loughran
            Priority: Minor


Currently YARN apps set up their classpath via the default value {{YarnConfiguration.DEFAULT_YARN_APPLICATION_CLASSPATH}}
or an overridden property {{yarn.application.classpath}}. 

If you don't have the classpath right, the AM won't start up. This means the client needs
to be explicitly configured with the CP.

If the node manager exported the classpath property via an env variable {{YARN_APPLICATION_CLASSPATH}},
then the classpath could be set up in the AM simply by referencing that property, rather than
hoping its setting is in sync.
