Subject [jira] [Commented] (YARN-2644) Recalculate headroom more frequently to keep it accurate
Date Sat, 04 Oct 2014 00:10:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14158759#comment-14158759
] 

Jian He commented on YARN-2644:
-------------------------------

Just one more thing:
- probably we can move {{headroomProvider}} field into LeafQueue. Update headroomProvider
info in the queue itself. {{FiCaSchedulerApp}} change can be simplified, it can get the headroomProvider
via the queue Reference.

> See parent (1198) for more detail - this specifically covers calculating the headroom
more frequently, to cover the cases where changes have occurred which impact headroom but
which are not reflected due to an application not being updated.
