Anoop Sam John commented on HBASE-16783:
----------------------------------------

First of all this is not a manger for the pool. This is a manager for the bufs 
(that too from pool or on demand created)
Now can u make use of the same BBLOS object for the remaining write as well? 
May be ugly.  But can the BBLOS at least open up a method to return the cur buf 
which can be used to retrieve the buf for writing the header+ message?


> Use ByteBufferPool for the header and message during Rpc response

> With ByteBufferPool in place we could avoid the byte[] creation in 
> RpcServer#createHeaderAndMessageBytes and try using the Buffer from the pool 
> rather than creating byte[] every time.
