Bikas Saha commented on YARN-417:
---------------------------------
Please do use join and make sure all the threads are complete and get cleaned
up. It may be a convenience to call stop() in the callback but I dont think we
should encourage that. It might be fine now but not future proof. Its not
uncommon for API's to require users to be well behaved. As far as such use
cases are concerned, since we have made this class an AbstractService, the
common use case would be to init and start the service in the beginning and the
stop it in the end, similar to other services.
