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.
> Exception when closing DFSClient while multiple files are open
