Hi Patrick,
Thank you for your reply. I owe you and the others on this list an apology.
It turns out I was creating the node twice, which I discovered after writing
a mini-program to demonstrate the problem and the mini-program didn't
have the problem. That caused me to go back and look at
Hi Leonard,
Between 00:43:23,035 and 00:43:23,157 I see client session
0x123730dbe6e0001 get 15 "node exists" exceptions in a row. Are you
expecting this? (ie are you attempting to create this node 15 times in a
row or is this unexpected? I can't tell from the client snippet you

I've just upgraded to ZooKeeper 3.2.0, testing the fix for ephemeral nodes

unexpected behavior:
The first time I call zoo_create() to create an ephemeral node, it returns
ZNODEEXISTS, even if the node didn't previously exist. It
Hi Todd,

Echo stat | nc localhost clientport

Is there a way to query an ensemble and find out who is the current
leader?
Along those lines, what facilities exist for interrogating the ensemble
and the ensemble members? I'm thinking (dreaming) of an API like:
Ensemble : object representing a zookeeper ensemble
Long Ensemble.getLastT
I forgot to mention this. You may also consider adding more zookeeper
servers and setting the weight of such servers to zero. We will be
introducing this possibility in 3.2.1 (the upcoming release). Zero-
weight servers simulate observers, but they do not behave exactly as a
observers, since
I agree with Mahadev that it sounds like a stretch. I just wanted to
point out that we have been working on a new feature that would
certainly help in this case: Observers (ZOOKEEPER-368). I don't think
we have decided yet in which release we will include it, but my
current guess is 4.0.0 a
