Date Sun, 28 Aug 2016 04:14:20 GMT

Arun Suresh updated YARN-5221:
    Attachment: YARN-5221.009.patch

Thanks for the thoughtful review [~subru]. Updating the patch to rebase with trunk and kick
of jenkins.

I have also updated it your suggestions, as part of which I have introduced an enum {{ContainerUpdateType}}
used both in the {{AllocateRequest}} to limit the update to either a Container capability
increase / decrease or ExecutionType.

bq. .. can we defer splitting increase/decreaseRequests to the actual Scheduler..
I totally agree. I wanted this patch to be more about refactoring / fixing the user facing
aspects of YARN-1651. I will raise another JIRA to refactor some of these internals.
