    Description

      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?
