[jira] [Created] (YARN-702) minicluster classpath construction requires user to set yarn.is.minicluster in the job conf

Sandy Ryza created YARN-702:
-------------------------------

             Summary: minicluster classpath construction requires user to set yarn.is.minicluster in the job conf
                 Key: YARN-702
                 URL: https://issues.apache.org/jira/browse/YARN-702
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 2.0.4-alpha
            Reporter: Sandy Ryza


YARN-129 improved classpath construction for miniclusters by, when yarn.is.minicluster is set, adding the current JVM's classpath to the ContainerLaunchContext for the MR AM and tasks.  An issue with this is that it requires the user to set yarn.is.minicluster on the mapreduce side in the job conf, if they are not copying to RM conf into the jobconf.

I think it would be better to bypass the ContainerLaunchContext and instead have the nodemanager check the property, and if it is true, do the classpath additions there.
