Subject [jira] [Updated] (YARN-41) The RM should handle the graceful shutdown of the NM.
Date Tue, 26 May 2015 18:02:19 GMT

     [ https://issues.apache.org/jira/browse/YARN-41?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.
