Arun Suresh created YARN-6963: --------------------------------- Summary: 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: Bug Reporter: Arun Suresh Assignee: Arun Suresh
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 (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
