    Description

      IPCUtil.buildCellBlock is used by both server and client. Server provides BoundedByteBufferPool for buffers reuse, client code does not do that. This results in additional memory pressure on a client side, because buffers are allocated on every call to IPCUtil.buildCellBlock.

      My own local tests (with patch) show approximately 8-10% reduction in object allocation rate on a client side (with HBASE-15479 as well).
