Harsh J commented on HADOOP-7176:
---------------------------------

This had already gone in 0.23.0 (per the tag sources). 0.24 is a non-existent 
version, so changed the Fix Version to point to 0.23.0 where this was 
apparently already completed.

> The FsShell commands are very tightly coupled together which makes it 
> necessarily hard to write new commands.  There is a lot of redundancy between 
> the commands, inconsistencies in handling of paths, handling of errors, and 
> correct return of exit codes.  The FsShell commands should be subclasses of 
> the fs.shell.Command class which is already being used by the -count command, 
> and is used by other commands like dfsadmin.
> This will serve as an umbrella bug to track the changes.
