Subject [jira] Created: (HDFS-1109) HFTP and URL Encoding
Date Fri, 23 Apr 2010 23:40:50 GMT
HFTP and URL Encoding
---------------------

                 Key: HDFS-1109
                 URL: https://issues.apache.org/jira/browse/HDFS-1109
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 0.20.2, 0.20.1, 0.20.3, 0.21.0, 0.22.0
            Reporter: Dmytro Molkov


We just saw this error happen in our cluster. If there is a file that has a "+" sign in the
name it is not readable through HFTP protocol.
The problem is when we are reading a file with HFTP we are passing a name of the file as a
parameter in request and + gets undecoded into space on the server side. So the datanode receiving
the streamFile request tries to access a file with space instead of + in the name and doesn't
find that file.

The proposed solution is to pass the filename as a part of URL as with all the other HFTP
commands, since this is the only place where it is not being treated this way. Are there any
objections to this?
