Is org.apache.zookeeper.ZooKeeper thread safe?
I've started walking through the code to check for mutability, and
although the first level children are protected, I haven't fully walked
the graph. Perhaps I should ask, is it supposed to be thread safe?

Hi Todd,
Sorry for the clutter/confusion. Usually
This repro's in both branch-3.2, and branch-3.2+patches(473, 479, 481).
Basically, it seems like the nodes are electing pd4-zook02 to be the
leader. However, pd4-zook02 seems to realize it's not supposed to be and
then disconnects everyone. Then they re-elect it again, and it loops
over and
of patches.

It should be in 479. Perhaps you have a stale version of the patch.

It isnt used anywhere else, so the svn co otherwise should be fine. We

Like most folks, our WAN is composed of various zones, some central
processing, some edge, some corp, and some in between (DMZs). In this
model, a given Zookeeper server will not have direct connectivity to all
of it's peers in the ensemble due to various security constraints. Is
this a problem?

SINGLE ENSEMBLE:
GROUP A : ZK Servers w/ read/write AND Leader Elections
GROUP B : ZK Servers w/ read/write W/O Leader Elections
So, we can craft this via Observers and Hiererarchial Quorum groups?
