How does ops update zookeeper (in a shared configuration scenario)?

Question

So far I haven't seen a good way of updating zookeeper. I am thinking of writing a web browser for zookeeper. Even then, the hierarchical key-value might not be intuitive. Another idea is for ops to update a MySQL table and then run a script to update Zookeeper which in turn notifies all the apps. Thoughts? What are the best practices?

Answer 1

There is an eclipse plugin that lets you do read/write operations. Coming in 3.4 is a Hue based web frontend to zookeeper. There is of course the zkCli command line tool that comes with the zk distribution.

The eclipse plugin is a little slow, but works quite well. The web app is faster, but has a dependency on the REST interface in 3.4

update: Exhibitor from Netflix also provides a reasonable GUI along with other pretty cool capabilities of managing a zookeeper ensemble.

Answer 2

There are couple of GUIs available that allow to create/edit/delete the nodes. I have personally tried node-zk-browser and zk-web and would recommend zk-web
