Zheng Hu commented on HBASE-21946:
----------------------------------
We've ported the patch of HDFS-3246 into our HDFS branch, so upload the
ByteBuffer pread patch for HBase here. Cann't trigger the hadoop QA now,
because our hadoop release can not be accessed in public repo now.
> Replace the byte[] pread by ByteBuffer pread in HFileBlock reading once
> HDFS-3246 prepared

> [~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.
