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: Allow setting maxResources for ad hoc queues

> 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.
