-----------------------------------

             Summary: Support HDFS specific 'shell' on command 'hdfs dfs' 
invocation
                 Key: HDFS-7368
                 URL: https://issues.apache.org/jira/browse/HDFS-7368
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs-client
            Reporter: Vinayakumar B
            Assignee: Vinayakumar B


* *hadoop fs* is the generic implementation for all filesystem implementations, 
but some of the operations are supported only in some filesystems. Ex: snapshot 
commands, acl commands, xattr commands.
* *hdfs dfs* is recommended in all hdfs related docs in current releases.

In current code  both *hdfs shell* and *hadoop fs* points to hadoop common 
implementation of FSShell.
It would be better to have HDFS specific extention of FSShell which includes 
HDFS only commands in future.
