-------------------------------------------
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.
