Brahma Reddy Battula updated YARN-6963: --------------------------------------- Target Version/s: 3.4.0 (was: 3.3.0) Bulk update: moved all 3.3.0 non-blocker issues, please move back if it is a blocker. > Prevent other containers from staring when a container is re-initializing > ------------------------------------------------------------------------- > > Key: YARN-6963 > URL: https://issues.apache.org/jira/browse/YARN-6963 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Arun Suresh > Assignee: Arun Suresh > Priority: Major > > Further to discussions in YARN-6920. > Container re-initialization will lead to momentary relinquishing of NM > resources when the container is brought down followed by re-claiming of the > same resources when it is re-launched. If there are Opportunistic containers > in the queue, it can lead to un-necessary churn if one of those opportunistic > containers are started and immediately killed. > This JIRA tracks changes required to prevent the above by ensuring the > resources for a container are 'locked' for the during of the container > lifetime - including the time it takes for a re-initialization. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
