Subject [jira] [Resolved] (MAPREDUCE-3859) CapacityScheduler incorrectly utilizes extra-resources of queue for high-memory jobs
Date Mon, 03 Jun 2013 01:06:21 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3859?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun C Murthy resolved MAPREDUCE-3859.
--------------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 2.1.0-beta)

I'm resolving this for MR1 since I'll need to open a separate YARN jira for branch-2.

Thanks Sergey!

> Imagine, we have a queue A with capacity 10 slots and 20 as extra-capacity, jobs which
use 3 map slots will never consume more than 9 slots, regardless how many free slots on a
cluster.
