Devaraj K updated YARN-41:
--------------------------
Attachment: YARN-41-7.patch
[~djp] I have updated the patch with review comments. Can you have a look into
this?
In the latest patch I have added a new NodeState i.e. SHUTDOWN.
bq. Add tests for new PB objects UnRegisterNodeManagerRequestPBImpl,
UnRegisterNodeManagerResponsePBImpl into TestYarnServerApiClasses.java.
I have added test for UnRegisterNodeManagerRequestPBImpl and I haven't added
test for UnRegisterNodeManagerResponsePBImpl since it doesn't have any state to
verify and no value add for test.
> The RM should handle the graceful shutdown of the NM.
