[jira] [Created] (HADOOP-8653) FTPFileSystem rename broken
Karel Kolman created HADOOP-8653:
------------------------------------
Summary: FTPFileSystem rename broken
Key: HADOOP-8653
URL: https://issues.apache.org/jira/browse/HADOOP-8653
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 2.0.0-alpha, 0.20.2
Reporter: Karel Kolman
The FTPFileSystem.rename(FTPClient client, Path src, Path dst) method is broken.
The changeWorkingDirectory command underneath is being passed a string with file:// uri prefix (which FTP server does not understand obviously)
