Dynamically Adding nodes to ZK Ensemble
Hello,
I would like to add ZK nodes dynamically to an ensemble. I have seen https://issues.apache.org/jira/browse/ZOOKEEPER-107 but I do not see any documentation on how to do this.
Can anyone give me some insight?
Thanks

Hi there,
When is 3.5 suppose to be released? We are about to roll out ZK into active development and soon to production.
Thanks,
Russ

Hi Russ,
This presentation gives brief idea about zookeeper cluster reconfig
mechanism:
http://www.slideshare.net/Hadoop_Summit/dynamic-reconfiguration-of-zookeeper
zookeeper 3.5.0 source has zkCli.sh utility which supports reconfig command
to
dynamically reconfigure the cluster.

Deepak

You should start it as whatever you want it to be in the new configuration.
In this case participant.
In fact if you start it as observer but try to add it to the ensemble as
participant reconfig may actually fail in some cases because you need a
quorum of voters from the new config to complete state transfer however
observers can't vote.

Hi,
I have to remove one node from the zookeeper cluster, and add new node
using incremental method.
>From the documentation it's not very clear whether new node config file
should add it's entry as observer and then update to participant.
Or it's ok to start zookeeper on new node being participant directly.
Thanks & Regards,
Deepak

Re: Dynamically Adding nodes to ZK Ensemble

Hi Deepak,
it should work fine, except that you won't be able to invoke the new
reconfig/getconfig/updateServerList APIs from an old client.
This means, for example, that if you add 2 servers to your ensemble, none
of the old clients will migrate to the new servers (this is
what the updateServerList does).
Regards,
Alex

Re: Dynamically Adding nodes to ZK Ensemble

Hi,
I have one query regarding dynamic zookeeper cluster reconfiguration.
I will be using zookeeper 3.5.0 as server, but I have an application
which uses zookeeper-3.4.5 client library API. Upgrading zookeeper client
version is bit difficult in my environment due to other dependencies.
Will 3.4.5 client work fine with 3.5.0 server during cluster reconfiguration
Or I must use 3.5.0 client in this case?
Thanks & Regards,
Deepak

Please post any issues you're having with Exhibitor on the Github site.

How do you have the shared configuration set? Is it S3? Shared file? Are there any errors in the log?

There was a bug with this. Make sure you have the latest version.

Jordan,
We are trying to use exhibitor... It is not working as I expect it to. I read through the docs (maybe I missed something) and I am not sure how I can do this.
I add a new zookeeper via the UI in exhibitor. It turns green and seems happy, then moments later... It disappears from the UI. But if I manually add it into the "com.netflix.exhibitor-rolling.servers-spec" and "com.netflix.exhibitor.servers-spec"
The REST API is not working for me either. Gives me invalid method even though I have nodemodification set to true...
Any help on this would be fantastic!
Thanks

The main reason why I ask, is because I need the ability to dynamically add ZK nodes to the ensemble. Is there a supported way to do this in 3.4.5?
Thanks,

Re: Dynamically Adding nodes to ZK Ensemble

There are log lists of patches available and issues for 3.5.0. There are only 7 blockers currently marked, though. Until we decide what to do with all those, we won't have a release. The bottom line is that we don't have a date, even though the general feeling is that we would like to have it soon. The are important features lined up for 3.5.0. It viable to have 3.4.6 shortly, though.

Hi Russ,
This presentation gives brief idea about zookeeper cluster reconfig
mechanism:
http://www.slideshare.net/Hadoop_Summit/dynamic-reconfiguration-of-zookeeper
zookeeper 3.5.0 source has zkCli.sh utility which supports reconfig command
to
dynamically reconfigure the cluster.
Regards,
Deepak
