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
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

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.

Do I get any read performance increase (similar to an

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,
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
