> In the previous implementation, one non-exclusive container allocation is
> possible when the missed-opportunity >= #cluster-nodes. And
> missed-opportunity will be reset when container allocated to any node.
> This will slow down the frequency of container allocation on non-exclusive
> node partition: *When a non-exclusive partition=x has idle resource, we can
> only allocate one container for this app in every
> X=nodemanagers.heartbeat-interval secs for the whole cluster.*
> In this JIRA, I propose a fix to reset missed-opporunity only if we have >0
> pending resource for the non-exclusive partition OR we get allocation from
> the default partition.
