Subject [jira] [Commented] (MAPREDUCE-4311) Capacity scheduler.xml does not accept decimal values for capacity and maximum-capacity settings
Date Tue, 12 Jun 2012 17:34:42 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293794#comment-13293794
] 

Tom White commented on MAPREDUCE-4311:
--------------------------------------

Looks good. It's a nit, but there are some unrelated formatting/import changes (e.g. TestApplicationLimits)
which shouldn't really be a part of this JIRA. Otherwise +1.

Also this should be marked as an incompatible change since some fields and methods of CapacitySchedulerConfiguration
have changed.

> 0.20 used to take decimal and this could be an issue on large clusters that would have
queues with small allocations.
