Terence Yim commented on TWILL-180:
-----------------------------------
Supposedly the failure can be get via the {{Future}} returned by the
{{teraminte()}} call. However, currently the {{YarnTwillController}}
implementation doesn't really reflect the failure state in the future.
> TwillController.onTerminated() should pass the exit status of the app to the
> callback

> Listening to this callback, a client can only find out whether an app has
> terminated, but now how. That makes it hard to distinguish error scenarios:
> Was the app killed by the user? Did it fail? Or did it successfully complete?
> There should be an easy way for the client to find out.
