> When navigating the ZKCli for problems the current naming of ZNodes for leader-election isn't easy to navigate. Noticed that the default cli behaviour of a space is that is is stored as data inside the path of the znode specified. I assume the ZK Java API is being alittle more 'powerful' but it would be nice to enable operators a easier native way to check the little things.
