So does this mean no contrib section?

We are investigating Ensemble and a key question came up: How does one add a
server to a running ensemble of Zookeeper servers in a 24/7 environment? If
I have a 3-server ensemble and traffic grows to the point where I need
another 2 servers, how do I add them without shutting everything down and

Speaking of the contrib section, what is the status of ZOOKEEPER-103?
Is it ready to be reevaluated now that 3.0 is out?

I doubt we're swapping, The machine we used to test has 12 GB of RAM
and little else active at the time. I think the main problem is the
heap being too small, so the GC has to run for longer trying to track
down objects to collect.

just a quick sanity check. are you sure your memory is not overcommitted? in
other words you aren't swapping. since the gc does a bunch of random memory
accesses if you swap at all things will go very slow.

That's very interesting results, a good job sleuthing. You might try the
concurrent collector?

I've answered the questions you asked previously below, but I thought
I would open with the actual culprit now that we found it. When I said
loading data before, what I was talking about was sending data via
Thrift to the machine that was getting disconnected from zookeeper.
This turned out to be t
Hi Greg,
As for cross datacenters, we have tested zookeeper cross data centers and
it works fine. The only thing is that you might have to tweak synclimit and
tickTime to a little higher values for Zookeeper.

We're thinking about using Zookeeper as our coordination service and
also for doing group membership in the Amazon Cloud. Currently our
applications are deployed in Amazon Cloud on multiple availability
zones (i.e. data centers), so this means that ZK nodes will be talking
across datacenters. I'm
