    Description

      In the email[1] with title: [VOTE] Merge branch HBASE-21879 (Reading HFile's Block to ByteBuffer directly) back to master.

      we had a discussion for backporting HBASE-21879 to branch-2, so that users of release 2.3.x can gain the performance improvement.

      Will do the backport for branch-2.
