[jira] [Commented] (MAPREDUCE-3451) Port Fair Scheduler to MR2

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600903#comment-13600903 ] 

Vitaly Kruglikov commented on MAPREDUCE-3451:
---------------------------------------------

[~pwendell@gmail.com]:
FairScheduler.apt.vm description for the "minResources" queue property doesn't say what the units are: megabytes or bytes? For example, mapreduce.map.memory.mb is in megabytes. Could you please clarify the units for "minResources"? Many thanks!

> The Fair Scheduler is in widespread use today in MR1 clusters, but not yet ported to MR2. This is to track the porting of the Fair Scheduler to MR2 and will be updated to include design considerations and progress.
