[jira] [Created] (YARN-7248) NM returns new SCHEDULED container status to older clients

Jason Lowe created YARN-7248:
--------------------------------

             Summary: NM returns new SCHEDULED container status to older clients
                 Key: YARN-7248
                 URL: https://issues.apache.org/jira/browse/YARN-7248
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.0.0-alpha2, 2.9.0
            Reporter: Jason Lowe
            Priority: Blocker


YARN-4597 added a new SCHEDULED container state and that state is returned to clients when the container is localizing, etc.  However the client may be running on an older software version that does not have the new SCHEDULED state which could lead the client to crash on the unexpected container state value or make incorrect assumptions like any state != NEW and != RUNNING must be COMPLETED which was true in the older version.
