Zhijie Shen updated YARN-422:
-----------------------------
Attachment: YARN-422.4.patch
Enhance NMClient it the following aspects:
1. For NMClientImpl, make stopping all the running containers optional and
enabled by default.
2. Introduce the container state into NMClientAsync. The state will be checked
to avoid the event of stopping a container happening before that of starting
the container.
3. Test cases are added to cover these two changes.
In addition, I incorporate the recent changes about YarnRemoteException and
IOException. NMClient throws the both exceptions as well. CallbackHandler takes
Throwable as parameter in case some future changes (either internal or
external) will introduce more kinds of exceptions.
