   @jojochuang 
     I issue this Jira is that HBase wishes HDFS-3246 is supported in branch-2.8.x.  HDFS-14483 is that backport HDFS-3246 ByteBuffer pread interface to branch-2.8.x.  But HDFS-14483 is blocked by not supporting ByteBuffer in DFSInputStream.  HDFS-8901 support ByteBuffer in DFSInputStream. So I issue this Jira that  only backport part of the conent of HDFS-8901 about byte[] to ByteBuffer. 
   
   And the existing tests cover it all, and I do unit test. 
   
    Could you suggest this issue to branch-2, branch-2.8 or HDFS-14483 direct support ByteBuffer in DFSInputStream?  I think this issue to branch-2.8 is relatively reasonable and the change is relatively small. Thank you.
