> 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.
