Allen Wittenauer commented on HDFS-7368:
----------------------------------------
-1
We should be trying to get rid of 'hdfs dfs' as much as possible and
encouraging the use of 'hadoop fs'. Despite what people think, there is
absolutely nothing unique to HDFS from an end-user or application perspective
that shouldn't be implemented in the common abstraction.
> Support HDFS specific 'shell' on command 'hdfs dfs' invocation

>
> * *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.
