Sunil G commented on YARN-2056:
-------------------------------
+1 This make sense. I have a doubt though.
*max_ignored_over_capacity* will help to avoid the jitter when container sizes
varies and some times we do a little more/less preemption from leaf queue than
its defined capacity. So more or less its boil down to the resource size of
containers. per-queue configuration for max_ignored_over_capacity will
definitely give more control than now, but still if heterogeneous applications
(in terms of container resource) keeps running same queue, it may be still hard
to get a correct value.
