Anoop Sam John updated HBASE-15525:
-----------------------------------
Attachment: HBASE-15525_V6.patch
Fixed 2 suggestions from Stack. Added a test for BBPool also. Will commit once
QA is fine.
Now the BoundedBBPool will be not used anywhere. Still keeping it. May be we
should remove it later. Not doing as part of this Jira.
> 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
