>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs
>            Reporter: Weihao Zheng
>            Priority: Major

> As discussed in HADOOP-6536, FileUtil#fullyDelete should not delete the 
> contents of the sym-linked directory when we pass a symlink parameter. 
> Currently we try to delete the resource first by calling deleteImpl, and if 
> deleteImpl is failed, we regard it as non-empty directory and remove all its 
> contents and then itself. This logic behaves wrong when local file system 
> cannot delete symlink to a directory because of faulty disk, local system's 
> error, etc. When we cannot delete it in the first time, hadoop will try to 
> remove all the contents of the directory it pointed to and leave an empty dir.
> So, we should add an isSymlink checking before we call fullyDeleteContents to 
> prevent such behavior.
