Subject [jira] [Commented] (YARN-1446) Change killing application to wait until state store is done
Date Fri, 13 Dec 2013 07:06:07 GMT

    [ https://issues.apache.org/jira/browse/YARN-1446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13847217#comment-13847217
] 

Zhijie Shen commented on YARN-1446:
-----------------------------------

Two minor comments about the tests:

1. Maybe it's good to write a test case for YarnClient.killApplication, because after the
change, it's no longer a single wrap of ApplicationClientProtocol.

2. Also, is it good to test transition to/from KILLING in TestRMAppTransitions

> When user kills an application, it should wait until the state store is done with saving
the killed status of the application. Otherwise, if RM crashes in the middle between user
killing the application and writing the status to the store, RM will relaunch this application
after it restarts.
