> 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.
