> Make priority of mapreduce tasks configurable
> ---------------------------------------------
>
> Key: MAPREDUCE-7464
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7464
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: liu bin
> Priority: Major
> Labels: pull-request-available
>
> 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.
