Chengwei Wang created MAPREDUCE-7274: ----------------------------------------
Summary: Enable to set running task limit when mapreduce job is running Key: MAPREDUCE-7274 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7274 Project: Hadoop Map/Reduce Issue Type: New Feature Reporter: Chengwei Wang MRv2 enabled users to control the number of map or reduce tasks running simultaneously by configuration _mapreduce.job.running.map.limit_ or _mapreduce.job.running.reduce.limit._ But users can only set limit number before submitting the job to rm. So, it's meaningful to enable users to set the limit of running map or reduce __ tasks, which can help users to restrict resource usage of job and give resources to high-priority job. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
