Arun C Murthy updated MAPREDUCE-5154: ------------------------------------- Attachment: MAPREDUCE-5154.patch Thanks for the quick check [~sandyr]. Here is the update with better docs. > staging directory deletion fails because delegation tokens have been cancelled > ------------------------------------------------------------------------------ > > Key: MAPREDUCE-5154 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5154 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: jobtracker > Affects Versions: 1.2.0 > Reporter: Sandy Ryza > Assignee: Sandy Ryza > Attachments: MAPREDUCE-5154.patch, MAPREDUCE-5154.patch, > MAPREDUCE-5154.patch > > > In a secure setup, the jobtracker needs the job's delegation tokens to delete > the staging directory. MAPREDUCE-4850 made it so that job cleanup staging > directory deletion occurs asynchronously, so that it could order it with > system directory deletion. This introduced the issue that a job's delegation > tokens could be cancelled before the cleanup thread got around to deleting > it, causing the deletion to fail. -- This message is automatically generated by JIRA.
