Date Tue, 18 Jun 2013 13:35:22 GMT

    [ https://issues.apache.org/jira/browse/HDFS-217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686706#comment-13686706

sathish commented on HDFS-217:

i have one doubt,iam running ftp server and after getting connecting by client to server,i
am going to change the current working directory(cwd) to some other directory,but every time
iam getting with the error code 550.
and my api is like this
success = ftpClient.changeWorkingDirectory("/upload");
 my logs are this
SERVER: 220 Service ready for new user.
SERVER: 230 User logged in, proceed.
SERVER: 550 No such directory.
Failed to change working directory. See server's reply.

can anyone pls tell what's the reason?

> An FTP server that sits on top of a distributed filesystem like HDFS has many benefits.
It allows the storage and management of data via clients that do not know HDFS but understand
other more popular transport mechanism like FTP. The data is thus managed via a standard and
more popular protocol, support for which is widely available.
> The idea is to leverage what is already available in Apache  http://mina.apache.org/ftpserver.html
and build on top of it. This FTP server can be embedded easily in hadoop and can easily be
programmed to talk to HDFS via an Ftplet which is run by the FTP server.
> Ideally there should be options to configure FTP server settings (in hadoop-default.xml)
which allows FTP server to be started when HDFS is booted.
