Íñigo Goiri commented on YARN-2889: ----------------------------------- For the first one, just use a different user name (say user1) in the new case; no point on changing others. The other tests don't go over the limit. Right now, with the new limit, we have three cases that I'd like to test: * We actually limit. Say 2 as we have now. * We don't limit with a -1 and we see that all of them pass. * We limit with a number higher of the requests. This would fully cover the new feature and not just rely. > Limit the number of opportunistic container allocated per AM heartbeat > ---------------------------------------------------------------------- > > Key: YARN-2889 > URL: https://issues.apache.org/jira/browse/YARN-2889 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager, resourcemanager > Reporter: Konstantinos Karanasos > Assignee: Abhishek Modi > Priority: Major > Attachments: YARN-2889.001.patch, YARN-2889.002.patch, > YARN-2889.003.patch > > > We introduce a way to limit the number of opportunistic containers that will > be allocated on each AM heartbeat. > This way we can restrict the number of opportunistic containers handed out > by the system, as well as throttle down misbehaving AMs (asking for too many > opportunistic containers). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
