      Description

      MPUs to HDFS fail as you can't concat an empty block. 

      Whatever uploads to HDFS needs to recognise that specific case "0-byte file" and rather than try and concat things, just create a 0-byte file there.

      Without this, you can't use MPU as a replacement for distcp or alternative commit protocols.
