Date Mon, 26 Sep 2016 12:48:20 GMT

     [ https://issues.apache.org/jira/browse/YARN-2009?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sunil G updated YARN-2009:
--------------------------
    Attachment: YARN-2009.0003.patch

Attaching new patch with user-limit support.

I think {{FifoIntraQueuePreemptionPolicy.computeAppsIdealAllocation}} became more complex.
I will try make it more simple in next patch.

> While preempting containers based on the queue ideal assignment, we may need to consider
preempting the low priority application containers first.
