>
>
> 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.
