Anoop Sam John commented on HBASE-12202:
----------------------------------------
Current work/idea is to continue the read from DFSClient to on heap only.(This
is to a byte[] now) The L2 cache will/can be offheap and then when HFileBlock
is being got from L2 cache avoid the need to copy to on heap. DFSClient read
part can be checked as next steps. (If you are experimenting with that great.
Will wait to see your analysis and test results)
> Support DirectByteBuffer usage in HFileBlock
