Jeff Hammerbacher commented on ZOOKEEPER-386:

I'm +1 on JLine. It's not as nice as Python's readline support but we used it 
in Hive to similar effect, and having history + tab completion is critical for 
shell usability.

> improve c and java cli shells

> ------------------------------------------------------------
> Possible improvements:
> Default host list to localhost:2181 when not given.
> Don't print a ton of debug, it looks like both cli_mt and zkCli.sh does this. 
> Make a simple ls that lists subnodes one line at a time and a simple cat that 
> lists only the node content, simple put etc.
> Shell with gnu readline capabilities and tab completion on node names would 
> be a big improvement of usability during testing and debugging.
