      Description

      Sahil Takiar 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.
