> MR-279: port MAPREDUCE-2324 to mrv2
> -----------------------------------
>
> Key: MAPREDUCE-2723
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2723
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans
> Fix For: 0.23.0
>
>
> MRV2 currently does not take reduce disk usage into account when trying to
> schedule a container. For feature parity with the original map reduce it
> should be extended to allow for disk space requests within containers along
> with RAM requests. We then also need to port MAPREDUCE-2324 to the scheduler
> to allow it to avoid starvation of containers that might never get the
> resources that they need.
