[jira] [Created] (SAMZA-308) Allow the container JVM to be customized

Martin Kleppmann created SAMZA-308:
--------------------------------------

             Summary: Allow the container JVM to be customized
                 Key: SAMZA-308
                 URL: https://issues.apache.org/jira/browse/SAMZA-308
             Project: Samza
          Issue Type: New Feature
          Components: yarn
    Affects Versions: 0.7.0
            Reporter: Martin Kleppmann


When running a container, the JAVA_HOME environment variable is currently inherited from the parent process (the JobRunner in the case of LocalJobFactory, the NodeManager in the case of YarnJobFactory). It would be nice to allow a job to specify a JAVA_HOME path as part of its configuration, so that a job can choose to run in a particular JVM version (e.g. allowing the YARN cluster and the jobs' JVM versions to be updated independently from each other).
