Subject [jira] [Commented] (MAPREDUCE-2649) MR279: Fate of finished Applications on RM
Date Thu, 11 Aug 2011 04:23:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13082900#comment-13082900

Thomas Graves commented on MAPREDUCE-2649:
------------------------------------------


I'm fine with the simpler model.  This algorithm was based on how the jobtracker does it now.
 It will simplify things a lot and we won't need a separate thread. 

If no one else has objects I'll make the changes.

> Today RM keeps the references of finished application for ever. Though this is not sustainable
long term, it keeps
> the user experience saner. Users can revisit RM UI and check the status of their apps.
> We need to think of purging old references yet keeping the UX sane.
