Hairong Kuang commented on HDFS-724:
------------------------------------
The timestamp meta information could be added to regular data packets as well.
My plan is not to send heartbeats periodically. Instead a heartbeat is sent
only if the connection is idle for too long time.
> Pipeline close hangs if one of the datanode is not responsive.

> In the new pipeline design, pipeline close is implemented by sending an
> additional empty packet. If one of the datanode does not response to this
> empty packet, the pipeline hangs. It seems that there is no timeout.
