That approach will cause issues when we bump JRuby to a newer version and 
altering the classpath in that way it will make difficult to keep things 
consistent. As I mentioned, this was caused by ZOOKEEPER-1718 and looking at 
master and branch-1 we still require ZooKeeper 3.4.6 so it shouldn't be a 
problem unless you are using a different version of ZK in your deployment.

Its better to have auto complete and proper zkcli prompt. However it impact 
hbase shell if jline jar is placed at hbase/lib, so we can place the jar at 
"hbase/lib/jline" and set it in the classpath on zkcli command.

We cannot bump JLine to a newer version since the version of JRuby we ship is 
an old one (see HBASE-13338). Also this shouldn't cause any issue to use zkcli 
since it only disables the auto complete functionality. Another option is to 
use a version of ZK that doesn't have ZOOKEEPER-1718.
