Subject [jira] [Commented] (YARN-128) Resurrect RM Restart
Date Tue, 06 Nov 2012 17:34:14 GMT

    [ https://issues.apache.org/jira/browse/YARN-128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13491635#comment-13491635
] 

Bikas Saha commented on YARN-128:
---------------------------------

Devaraj, I think the current approach+code based on zkstore (that YARN-128.patch builds on
top of) has some significant issues wrt perf/scalability of ZK/future HA. The design outline
attached to this jira calls out some of the issues. The next proposal document will help clarify
a bit more I hope.
