> Enable to limit running map and reduce tasks when job is running
> ----------------------------------------------------------------
>
> Key: MAPREDUCE-7274
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7274
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: mr-am, mrv2
> Affects Versions: 3.2.0
> Reporter: Chengwei Wang
> Priority: Major
> Attachments: MAPREDUCE-7274-branch-3.2.0.patch
>
>
> 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 when job is running, which can help
> users to restrict resource usage of job and give resources to high-priority
> job.
