haosdent commented on YARN-1549:
--------------------------------
In RMAppImpl.java, the comments tell us "If this is an unmanaged AM, we are
safe to unregister since unmanaged AM will immediately go to FINISHED state on
AM unregistration". But I couldn't found any codes relates to this.
{code:java}
@Override
public boolean isAppSafeToTerminate() {
RMAppState state = getState();
return state.equals(RMAppState.FINISHING)
|| state.equals(RMAppState.FINISHED) || state.equals(RMAppState.FAILED)
|| state.equals(RMAppState.KILLED) ||
// If this is an unmanaged AM, we are safe to unregister since unmanaged
// AM will immediately go to FINISHED state on AM unregistration
getApplicationSubmissionContext().getUnmanagedAM();
}
{code}
