liu bin created MAPREDUCE-7464: ---------------------------------- Summary: Make priority of mapreduce containers configurable Key: MAPREDUCE-7464 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7464 Project: Hadoop Map/Reduce Issue Type: Improvement Reporter: liu bin
When maps and reduces run simultaneously, if resources are insufficient, reduces will be preempted. Because the priority of reduce is higher than map, the preempted reduces will first obtain resources when rerun, and then be preempted again, falling into a loop. We need to configure the priority of map higher than reduce to avoid this situation. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-dev-h...@hadoop.apache.org
