Eli Collins commented on HADOOP-6536:
-------------------------------------

+1 Ravi's proposal. I would also add that fullyDelete should delete dangling 
links (it currently does but we should add a test). The current behavior is due 
to java making it difficult to identify symlinks.

> FileUtil.fullyDelete(dir) behavior is not defined when we pass a symlink as 
> the argument

> FileUtil.fullyDelete(dir) deletes contents of sym-linked directory when we 
> pass a symlink. If this is the behavior, it should be documented as so. 
> Or it should be changed not to delete the contents of the sym-linked 
> directory.
