Subject [jira] [Commented] (YARN-5889) Improve user-limit calculation in capacity scheduler
Date Mon, 09 Jan 2017 20:19:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15812737#comment-15812737

Eric Payne commented on YARN-5889:
----------------------------------

[~sunilg],
bq. However, I do think {{reComputeUserLimits}} needs to be modified to update {{preComputedUserLimit}}
when recomputing user limits. That is not done anywhare in the current patch.
Actually, we may want to have separate methods for {{reComputeUserLimits}} and {{reComputeActiveUserLimits}}

> Currently user-limit is computed during every heartbeat allocation cycle with a write
lock. To improve performance, this tickets is focussing on moving user-limit calculation out
of heartbeat allocation flow.
