Subject [jira] [Commented] (YARN-1378) Implement a RMStateStore cleaner for deleting application/attempt info
Date Tue, 12 Nov 2013 22:19:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-1378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13820553#comment-13820553

Bikas Saha commented on YARN-1378:
----------------------------------

I would like us to measure before committing to this change. If the time taken to load so
much state is too large then the approach taken by the current solution would be a non-starter
right? Doesnt harm in measuring before committing the change since this patch isnt really
blocking anything, right?

> Now that we are storing the final state of application/attempt instead of removing application/attempt
info on application/attempt completion(YARN-891), we need a separate RMStateStore cleaner
for cleaning the application/attempt state.
