> [~stakiar] is working on HDFS-3246, so now we have to keep the byte[] pread
> in HFileBlock reading. Once it get resolved, we can upgrade the hadoop
> version and do the replacement.
> I think it will be a great p999 latency improvement in 100% Get case, anyway
> file a issue address this firstly.
