-------------------------------------
Summary: 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: 2.0.3-alpha
Reporter: Sandy Ryza
Assignee: Sandy Ryza
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.
