current leader

[Avinash Lakshman <av...@gmail.com>]

Is there any API to get information of the current leader of the ZK cluster
and/or to register for leader change notifications? Also any API to get the
endpoint information of the members of the cluster?

Thanks
Avinash

We've talked before about putting that information into /zookeeper (ie
as a znode). As long as auth can be applied to these znodes, similar
to the rest of the space, it seems like a good place to me.

I think JMX can atleast give you what the stat of a given zk server is (
http://zookeeper.apache.org/doc/r3.3.3/zookeeperJMX.html) but i dont think
you'd be able to register for change notification.

Am interested in hearing any thoughts on a nice api for notifications
though.

thanks
