Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0

Assignee: Todd Lipcon
Priority: Blocker
The DefaultContainerExecutor currently has code that removes the application
dir from appcache/ in the local directories on every task localization. This
causes any concurrent executing tasks from the same job to fail.
