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?

Was it helpful?

Solution

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.

  2. http://wiki.apache.org/hadoop/ZooKeeper/GSoCMonitoringAndWebInterface

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.

OTHER TIPS

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
