> When the client is writing slowly, the client will send a heartbeat to signal 
> that the connection is still alive.  This case works fine.
> However, when a client is writing fast but some of the datanodes in the 
> pipeline are busy, a PacketResponder may get a timeout since no ack is sent 
> from the upstream datanode.  We suggest that the last datanode in a pipeline 
> should send a heartbeat when there is no traffic.
