Kihwal Lee commented on HDFS-3541:
----------------------------------
With the proposed fix, the DataXceiver thread would break out of
responder.join(), but wouldn't PacketResponder keep running and do
finalizeBlock() and closeBlock()? It would even try to send an ack back, which
would probably fail anyway.
Rather than letting PacketResponder asynchronously modify the state, can we
make it stop?
