> Add option to not kill already-done map tasks when node becomes unusable
> ------------------------------------------------------------------------
>
> Key: MAPREDUCE-7168
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7168
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: mrv2
> Affects Versions: 2.9.2
> Environment: Google Compute Engine (Dataproc), Java 8
> Reporter: Mikayla Konst
> Assignee: Mikayla Konst
> Priority: Minor
> Attachments: MAPREDUCE-7168.patch
>
>
> When a node becomes unusable, if there are still reduce tasks running, all
> completed map tasks that were run on that node are killed so that they can be
> re-run on a different node. This is because the node can no longer serve
> shuffle data, so the map task output cannot be fetched by the reducers.
> If map tasks do not write their shuffle data locally, killing already-done
> map tasks will make the job lose map progress unnecessarily. This change
> prevents map progress from being lost when shuffle data is not written
> locally by providing a property mapreduce.map.rerun-if-node-unusable that can
> be set to false to prevent killing already-done map tasks.
