Steve Loughran commented on HADOOP-14559:
-----------------------------------------
Closing things is always good due diligence...the codepaths do need to handle
failure to setup though.
How about we move to a field {{FTPFileSystem ftp}}, with a teardown method
calling {{IOUtils.closeStream(ftp)}}.
> The used FTPFileSystem in TestFTPFileSystem should be closed in each test
> case.
