Description

The background is the hadoop production clusters we used internally is based on Hadoop 2.7.3. Currenlty we maintain an internal OzoneFS client for Hadoop 2.7.3. With HDDS-3627 merged, it is the right time to use the community version instead of an internal version.

The improvement are some Hadoop2.7.7 newly added functions which are not available in 2.7.3. So refact the code to use an older version with same functionality.
