    Description

      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.
