Config management and group membership are two of the simplest use cases
for ZK, we don't have a "recipe" here as it's pretty basic (not that we
couldn't/shouldn't)
The java example in our docs is pretty close, it sets a watch on a node
and monitors for changes. This is the typical pattern for CM.

Also:
Tom White's excellent book on Hadoop does a great job covering ZooKeeper
in chapter 13, it's available on safaribooks or for purchase if that
works for you:

Hey
I am a newbie to ZooKeeper and be happy if someone could link me to a
good example how ZooKeeper can be used for configuration management?
Thanks.
