Description

Here is related code:

      userAndPassword = (conf.get("fs.ftp.user." + host, null) + ":" + conf
          .get("fs.ftp.password." + host, null));
      if (userAndPassword == null) {
        throw new IOException("Invalid user/passsword specified");
      }

The intention seems to be checking that username / password should not be null.
But due to the presence of colon, the above check is not effective.
