Benjamin Gufler updated HADOOP-3639:
------------------------------------

    Release Note: Fixes HADOOP-3639
          Status: Patch Available  (was: Open)

Replaces the iterator with direct access to the map of open files. Since closing a file removes it from the map, there is no need to clear the map at the end.

> 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.
