Subject [jira] [Closed] (FTPSERVER-434) Cannot use FTP commands with Hadoop 1.0.3
Date Tue, 25 Sep 2012 20:18:09 GMT

     [ https://issues.apache.org/jira/browse/FTPSERVER-434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Niklas Gustavsson closed FTPSERVER-434.
---------------------------------------

    Resolution: Won't Fix
      Assignee: Niklas Gustavsson

HDFS-over-FTP is not part of FtpServer, so you will probably have more luck asking the developers
of the HDFS-over-FTP project, e.g. at https://github.com/iponweb/hdfs-over-ftp
