    Description

      I'd like to propose refactoring DFSClient to extract DFSOutputStream and DFSInputStream into a new org.apache.hadoop.hdfs.client package. DFSClient has become unmanageably large, containing 8 inner classes.and approaching 4kloc. Factoring out the non-static inner classes will also make them easier to test in isolation.
