Subject [jira] [Commented] (YARN-4702) FairScheduler: Allow setting maxResources for ad hoc queues
Date Tue, 16 Aug 2016 21:34:22 GMT

    [ https://issues.apache.org/jira/browse/YARN-4702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15423419#comment-15423419

Karthik Kambatla commented on YARN-4702:

Thinking more about this, we should avoid supporting minChildResources even if that means
an incomplete set of configs for ad hoc child queues. 

Comments on the patch:
# It appears one could use this to set maxResources for non-adhoc child queues as well. Can
we prevent that? 
# Do we need a check to assert {{maxChildQueueResources < maxQueueResources}}?
# Nice tests and thanks for cleaning up the javadocs etc.

> FairScheduler allows creating queues on the fly. Unlike other queues, one cannot set
maxResources for these queues since they don't show up in the xml config. Adding a default
maxResources for ad hoc pools would help.
