Ravi Gummadi commented on HADOOP-6536:
--------------------------------------
Since when symlink to a file is sent as param to fullyDelete(), it deletes the
symlink only(and not the file pointed to by symlink), I think fullyDelete()
should only delete the symlink even when symlink to a dir is passed as
param(and should not delete the dir pointed to by symlink).
> 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.
