May be you are misunderstanding the way Zookeeper works. It is
basically a remote file system with a lot of guaranties regarding
distributed operations in the files and folders, aka znodes. So, like you
would normally do in a file system, you just turn it on and use. There is
an executable you may start "/bin/zkServer.sh start-foreground".
From the client side you may create and observe znodes. I have a simple
demo project that I use here in Brazil, for training and conferences, it's
variables and classes are in Portuguese but you may take o look. Also there
is some code sample in the code tree, in src/recipes/.
