ramkrishna.s.vasudevan commented on HBASE-15212:
------------------------------------------------
I think sooner we will be moving over to Offheap Memstore and offheap in write
path. I think once that happens we have to fine tune other parameters also like
flush related params as many of that are dependent on the heap Xmx which may
become irrelevant to an extent once we go to Offheap.
> RRCServer should enforce max request size

> A TODO from HBASE-15177 was that we are not protecting the RPCServer in case
> an RPC request with a very large size is received. This might cause the
> server to go OOM because we are allocating the RPC serialization into a BB.
> Instead we should reject the RPC and close the connection.
