Subject [jira] [Created] (MAPREDUCE-6669) Jobs with encrypted spills don't tolerate AM failures
Date Tue, 05 Apr 2016 06:09:25 GMT
Karthik Kambatla created MAPREDUCE-6669:
-------------------------------------------

             Summary: Jobs with encrypted spills don't tolerate AM failures
                 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.
