-----------------------------------
Attachment: WIP.patch
Parking an initial version of patch for high level review.
I have not removed BoundedByteBufferPool.. Added ByteBufferPool newly which
deals with fixed sized BBs. We dont need both any way.
Will make final patch by begin of next week.
> OutOfMemory could occur when using BoundedByteBufferPool during RPC bursts

>
> After HBASE-13819 the system some times run out of direct memory whenever
> there is some network congestion or some client side issues.
> This was because of pending RPCs in the RPCServer$Connection.responseQueue
> and since all the responses in this queue hold a buffer for cellblock from
> BoundedByteBufferPool this could takeup a lot of memory if the
> BoundedByteBufferPool's moving average settles down towards a higher value
> See the discussion here
