Arun Suresh updated YARN-6406: ------------------------------ Fix Version/s: (was: 2.9.0) > Remove SchedulerRequestKeys when no more pending ResourceRequest > ---------------------------------------------------------------- > > Key: YARN-6406 > URL: https://issues.apache.org/jira/browse/YARN-6406 > Project: Hadoop YARN > Issue Type: Improvement > Affects Versions: 2.8.0, 2.7.3, 3.0.0-alpha2 > Reporter: Arun Suresh > Assignee: Arun Suresh > Fix For: 3.0.0-alpha3 > > Attachments: YARN-6406.001.patch, YARN-6406.002.patch > > > YARN-5540 introduced some optimizations to remove satisfied SchedulerKeys > from the AppScheduleingInfo. It looks like after YARN-6040, > ScedulerRequestKeys are removed only if the Application sends a 0 > numContainers requests. While earlier, the outstanding schedulerKeys were > also remove as soon as a container is allocated as well. > An additional optimization we were hoping to include is to remove the > ResourceRequests itself once the numContainers == 0, since we see in our > clusters that the RM heap space consumption increases drastically due to a > large number of ResourceRequests with 0 num containers. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
