Haibo Chen reassigned MAPREDUCE-6669:

>                 Key: MAPREDUCE-6669
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6669
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mr-am
>    Affects Versions: 2.8.0
>            Reporter: Karthik Kambatla

>            Priority: Critical

> The key used for encrypting intermediate data is not persisted anywhere, and hence can't
be recovered the same way other MR jobs can be. We should support recovering these jobs as
well, hopefully without having to re-run completed tasks.
