      Description

      Server.java
                if (!RpcConstants.HEADER.equals(dataLengthBuffer)
                    || version != CURRENT_VERSION) {
                  //Warning is ok since this is not supposed to happen.
                  LOG.warn("Incorrect header or version mismatch from " + 
                           hostAddress + ":" + remotePort +
                           " got version " + version + 
                           " expected version " + CURRENT_VERSION);
                  setupBadVersionResponse(version);
                  return -1;
      

      This message should include the value of RpcConstants.HEADER and dataLengthBuffer in addition to just the version information or else that data is lost.
