Maybe we should have a contrib pkg for utilities such as this? I could see a python script that, given 1 server (might require addl 4letter words but this would be useful regardless), could collect such information from the cluster. Create a JIRA?

It's not possible. You need to query all the servers in order to know

It should be pretty simple to implement this by parsing the output
from the 'stat' 4-letter command.

Is there a way to see the current leader and a list of followers from a
single node in the ZK quorum? It seems that ZK monitoring (JMX, 4-letter
commands) only provides info local to a node.
