Suresh Srinivas commented on HADOOP-5859:
-----------------------------------------
# Remove commented line setting maxPacket to 1000
# {{DataStreamer.run()}} No need to set {{response}} to null, because
closeResponse() called prior, sets the response to null
# {{DataStreamer.run()}} code could be refactor to use closeStream() method
instead of duplicating the code to close {{blockStream}}. A flag could be
passed to indicate indicate end-of-block.
# {{ResponseProcessor.processDataNodeError()}} could use closeStream method.
> FindBugs : fix "wait() or sleep() with locks held" warnings in hdfs
