I believe jira 346 is saying that JMX could be used, not that it
currently has that capability. I took a look at the current beans and
I can't find a current method that implements shutdown (kill). As of
today the best way to kill the server is as Mahadev suggests.

this assertion before and it always irked me a bit, but Ryan's
scenario is a great thought experiment (well, though experiment for US, not
for him). Why can't those clients decide the session is expired after 3
days when the timeout is 3 minutes?

Those are pretty short timeouts, many sources of delay could be
causing this. Network jitter/latency, GC/swap (server or client), IO
write latency, etc... See if any of this might be your issue:

The client seeing the problem in this case is 3.3.0, I see this based
on the line number in the stack trace not matching up with 3.3.3, with
3.3.0 it's this line:
event.setPath(serverPath.substring(chrootPath.length()));
so for some reason your chroot path is negative in length?
Perhaps the client is failing while writing the request? (that's what
the eof seems to indicate) Does the server side exception always look

This is being caused by a regression introduced by ZOOKEEPER-1136, see
my comments on https://issues.apache.org/jira/browse/ZOOKEEPER-1319
This is a serious regression, I've talked with Mahadev and we'll be
rolling a 3.4.1 soon to address it. (either later this week or early
next)

Stefan,
It mostly looks like

confirm can you do this -
do a get on the same znode
I believe this can effect not just 3.3-3.4 upgrades but also normal
operation of a 3.4 cluster. I'd suggest holding off on 3.4 until 3.4.1
is available. (Mahadev and I are working on it for RC later this week,
a patch should be available soon).

The client bindings are responsible for maintaining a heartbeat with
the service:

there's nothing you need to do here from your application's
perspective. If the TCP connection is lost btw the client and server
(or any
Good idea Mahadev. Let's just be (more) explicit in our messaging
about what's production ready and what's not.

No idea - we have no control over third-party mirroring. Sounds like
your best bet would be to set p.a.o as a repo in your pom.

who does control mirroring on repo1.maven.org? Anyone know? Is this
Apache? (you might check wth Apache Infra)

Hi all,

Take a look at whirr. http://whirr.apache.org/
That said, it's not clear to me what you mean. every time a new
instance is spawned zk will run on it. Surely you don't mean a zk
server (the max you might run is say 5 or perhaps 7 servers), however
if it's a client then you'd be including the zk
from what I understood is I basically have to run the whirr launch
cluster command 10 times?
Yes. That will do it.

The admin guide is not helpful in this regard? If there are bits
missing the community would benefit if you entered jiras highlighting
the shortfall.
