------------------------------------------------
Hi Benjamin, the file patch-dfs-close-v2 has some repeated codes and so it
cannot be compiled. Since the test is simple, could you move it to
TestDistributedFileSystem? Also, you need to shutdown the MiniDFSCluster
object. See TestDistributedFileSystem.testFileSystemCloseAll() as an example.

> DFSClient.close uses an iterator for closing files which are still open.
> Closing a file removes that file from the list of open files, which in turn
> breaks the iterator.
