Omkar Vinit Joshi commented on YARN-661:
----------------------------------------
I guess we need 2 features in deletion service.
* A way for user to specify that delete all the sub directories and files
inside a parent directory but don't delete parent directory.
* A way to define dependency between deletion tasks. For example we need to
delete usercache files before actually deleting the parent usercache itself...
> NM fails to cleanup local directories for users

> Key: YARN-661
> URL: https://issues.apache.org/jira/browse/YARN-661
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.1.0-beta, 0.23.8
> Reporter: Jason Lowe
> Assignee: Omkar Vinit Joshi
>
> YARN-71 added deletion of local directories on startup, but in practice it
> fails to delete the directories because of permission problems. The
> top-level usercache directory is owned by the user but is in a directory that
> is not writable by the user. Therefore the deletion of the user's usercache
> directory, as the user, fails due to lack of permissions.
