Hi all,
We're using Zookeeper for Leader Election and system monitoring. We're
also using it for synchronizing our cluster wide jobs with barriers. We're
running into an issue where we now have a single job, but each node can fire
the job independently of others with different criteria in the
Hey guys,
Forgive me if this is documented somewhere, but I can't find an
answer. Our application is not enormous, so we will be using 4
application nodes that will also initially run Zookeeper. As our load
increases, Zookeeper will be moved to nodes that only run ZK and no
other processes.

Thanks for that Dave. If I do not configure it as an observer just a
normal member, what will the last even node to join do?

Do I get any read performance increase (similar to an

the node will not have a voting role?
to be alive is still three - it doesn't drop down to two. The majority
is of all voting servers, alive or dead.
Hope this helps -

Hi all,
I'm running into a strange issue I could use a hand with. I've
implemented leader election, and this is working well. I'm now
implementing a follower queue with ephemeral nodes. I have an interface
IClusterManager which simply has the api clusterChanged. I don't care
if nodes are

Hi all,
I'm writing a distributed queue monitoring class for our leader node in
the cluster. We're queueing messages per input hardware device, this queue
is then assigned to a node with the least load in our cluster. To do
