Subject [jira] [Created] (MAPREDUCE-6638) Jobs with encrypted spills don't recover if the AM goes down
Date Fri, 19 Feb 2016 16:28:18 GMT
Karthik Kambatla created MAPREDUCE-6638:
-------------------------------------------

             Summary: Jobs with encrypted spills don't recover if the AM goes down
                 Key: MAPREDUCE-6638
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6638
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster
    Affects Versions: 2.7.2
            Reporter: Karthik Kambatla
            Priority: Critical


Post the fix to CVE-2015-1776, jobs with ecrypted spills enabled cannot be recovered if the
AM fails. We should store the key some place safe so they can actually be recovered. If there
is no "safe" place, at least we should restart the job by re-running all mappers/reducers.
