[jira] Commented: (HADOOP-6536) FileUtil.fullyDelete(dir) behavior is not defined when we pass a symlink as the argument

["Ravi Gummadi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-6536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12828974#action_12828974 ] 

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) 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.
