Description

This code part is severely duplicated across the Hadoop repo:

  public static boolean isApplicationFinalState(YarnApplicationState appState) {
    return appState == YarnApplicationState.FINISHED
        || appState == YarnApplicationState.FAILED
        || appState == YarnApplicationState.KILLED;
  }

This functionality is used heavily by the log aggregation as well, so we may do some sanitizing here.
