Subject [jira] [Commented] (YARN-313) Add Admin API for supporting node resource configuration in command line
Date Wed, 12 Aug 2015 16:38:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14693784#comment-14693784

Junping Du commented on YARN-313:

Thanks [~elgoiri] for rebasing the patch!

bq. Unless the patch is ready to go and the JIRA is a critical fix, we'll defer it to 2.6.2.
Let me know if you have comments. Thanks!
Agree to the defer. I think we should target it to 2.8 as the whole feature is expected to
be ready in that timeline. 

bq. I would appreciate ideas on why this change breaks the refreshNodes with a graceful period.
It is because following code to check args number is not true any more when we have gracefully
decommission get in recently. 
+        "-refreshNodes".equals(cmd) || "-refreshResources".equals(cmd) ||
Remove "-refreshNodes".equals(cmd)" should make test pass.
