      Description

      The requested range may not be committed when the following happens:
      1. the last pending write is removed from the queue to write to hdfs
      2. a commit request arrives, NFS sees there is not pending write, and it will do a sync
      3. this sync request could flush only part of the last write to hdfs
      4. if a file read happens immediately after the above steps, the user may not see all the data.
