Suresh Srinivas commented on HDFS-537:
--------------------------------------
This change makes the existing code lot cleaner. Some minor comments:
# minor chage: BlockReceiver.java - setBytesAcked(), setNumBytes(), and other
methods can check to see if the value passed is greater than what it already
has. In that case, ReplicaInPipeline can ignore the passed value. This reduces
code where these set methods are used.
# ReplicaInPipeline.createStreams() - not sure if the REMIND command is
actionable and should be carried forward :-)
> DataNode uses ReplicaBeingWritten to support dfs writes/hflush
