We run secure client port at 2182 and standard port 2181. This 2181 is in
the dynamic config strings. Then we have a firewalld rule to block incoming
traffic on 2181.
For us this works, no problem with Curator Ensemble tracker either if I
recall. Our Curator based clients connect fine on the
Hi Yong,
When you run an operation on a node you will mostly get
ConnectionLossException, which you can retry. When the client connects to
ZK again after session expiration time is exceeded and it gets a session
expired notice, your node operation will also get a
SessionExpiredException. The
Hi George,
As a Zookeeper user or developer you should not have to care about which ZK
is the leader. What would be the use case of that?
Leader election is automatic and the clients can connect to any of the zk
cluster members regardless of role.

If you want to get rid of log4j1 in your existing Zookeeper installations,
you could also take the following approach :
Reload4j is the direct continuation / replacement of log4j1.
Stop zookeeper.
From the zookeeper/lib directory, remove log4j and slf4j-log4j.
Download reload4j and
If you want to run a zookeeper cluster you have to start with at least 2
members. From there you can scale up with the dynamic reconfig commands.

Parent nodes have an IP address as value.

Hi Prashant,
correct it only checks the local node. We built a script that parses the
dynamic config file and goes over all the nodes to report their status. You
can do this easily from shell by enabling adminserver functionality and
issuing curl http://yourzookeepernode.com:8081/commands/stats

Hi,
we're working on securing our clusters. For quorum, once we set
sslQuorum=true, there is no more unsecured quorum port.
Is such an option available or in the works for the client port as well ?
Or is ssl client port always in addition to unsecured client port ?

Chris

Let me write this from memory. :)
We have the following:
-A running zookeeper cluster with adminserver enabled
-One or more balancer client processes (one per datacenter), of which one
has a master role through some leader election. The master does the work,
the others do nothing.
-In our case,
