Subject [jira] [Updated] (YARN-4143) Optimize the check for AMContainer allocation needed by blacklisting and ContainerType
Date Tue, 14 Jun 2016 17:48:27 GMT

     [ https://issues.apache.org/jira/browse/YARN-4143?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daniel Templeton updated YARN-4143:
-----------------------------------
    Attachment: YARN-4143.002.patch

Since [~adhoot] doesn't seem to be working on this one anymore, I just rebased it and posted
a new patch.  This patch turns out to be considerably simpler than its predecessor because
some of the cleanup that was in the original patch made it in already.  [~sunilg], wanna have
a look?

> In YARN-2005 there are checks made to determine if the allocation is for an AM container.
This happens in every allocate call and should be optimized away since it changes only once
per SchedulerApplicationAttempt
