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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
