Xuan Gong commented on YARN-71:
-------------------------------

The approach I am using:
1. rename the folder (local files are not always belong to NM_user, So, rename the parent folder instead of files)
2. find the files' or dir's ownership and schedule the deletion, then delete them at the back-end.

> We have to make sure that NodeManagers cleanup their local files on restart.
> It may already be working like that in which case we should have tests validating this.
