ramkrishna.s.vasudevan commented on HBASE-17035:
------------------------------------------------
Similarly in FanoutFSOutput we have waitingAckQueue.
The AckHandler#completed() call does remove from this deque. Am not sure if
this AckHandler#channelRead0 is going to be sequential. We add in flushBuffer
to this queue and we remove in this AckHandler thread.
Is this fine? I don't know this model of netty so wanted to confirm once.
> Check why we roll a wal writer at 10MB when the configured roll size is 120M+
