Hi,
Is it possible to read znodes directly from snapshot and log files instead
of usign ZooKeeper API. In case a ZK ensemble is not available, can I login
to all available nodes and run a utility that will dump all znodes?
Thanks.

until the session timeout is exceeded)

Hi All,
Can you please share your experience regarding ZK snapshot retention and
recovery policies?
We have an application where we never need to rollback (i.e., revert back to
a previous state by using old snapshots). Given this, I am trying to

I remember Ben had opened a jira for clock jumps earlier:

have clocks jump forward in virtualized environments.
It is desirable to modify ZooKeeper to handle this situation (as much as
possible) internally. It would

I haven't give it a serious thought yet, but I don't think it is

Hi Qing,
Can you list the znodes from the monitor and from the node that the monitor
is restarting (run zkCli.sh on both machines).
I am curious to see if the node that did not receive the SESSION_EXPIRED
event still has the znode in its database.
Also can you describe your setiup? Can you send
In my case, I am pretty sure that the configuration was right. I will
reproduce it and post more info later. Thanks.

Can you explain why running ZK in embedded mode can cause znode

Thanks.

I am seeing a lot of these messages in our application. I would like to know

We have embedded ZK server in our application. We start a thread in our
application and call QuorumPeerMain.InitializeArgs().
When cleaning-up ZK we call QuorumPeerMain.shutdown() and wait for the
thread that is calling InitializeArgs() to finish. These two steps are
taking around 60
Hi All,
Since ZooKeeper does not support secure network connections yet, I thought I
would poll and see what people are doing to address this problem. Is anyone
running ZooKeeper over secure channels (client - server and server- server

Well looks like FastLeaderElection.shutdown() is not invoked. This has been
in 3.3.0. Should have checked on that earlier :-)

Hi,
Good question. We are planning to do something similar as well and it will
great to know if there are any issues with embedding ZK server into an app.
We simply use QourumPeerMain and QourumPeer from our app to start/stop the
ZK server. Is this not a good way to do it?

Hi,
I am trying to run systest on a 3 node cluster (

When I reach the 4th step which is to actually run the test I get exception
