Ivan Kelly commented on BOOKKEEPER-620:
---------------------------------------
New patch addresses comments except for 3. If there's an I/O error in a netty
socket, the channelDisconnected callback is called, so setting the channel to
disconnected on write request failures is unnecessary. Also, I'd like to
minimise the number of the place we modify state to make things simpler.

> channel & state are not synchronized in PerChannelBookieClient#closeInternal.
> so it might cause state is set to CONNECTED but the netty channel is closed
> by mistake in closeInternal.
