Subject [jira] [Resolved] (YARN-751) CLONE - CapacityScheduler incorrectly utilizes extra-resources of queue for high-memory jobs
Date Mon, 03 Jun 2013 03:29:21 GMT

     [ https://issues.apache.org/jira/browse/YARN-751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun C Murthy resolved YARN-751.
--------------------------------

    Resolution: Invalid

I verified that this doesn't happen in YARN. The user-limit computation is significantly different
and hence a non-issue.

use 3 map slots will never consume more than 9 slots, regardless how many free slots on a
cluster.
