> Today unmanaged AM client is waiting for app state to be Accepted to launch
> the AM. This is broken since we changed in YARN-1493 to start the attempt
> after the application is Accepted. We may need to introduce an attempt state
> report that client can rely on to query the attempt state and choose to
> launch the unmanaged AM.
