Hi there,

Could anyone update me on the project status for ES zookeeper? Is it still being maintained for newer versions (e.g. 0.90.xx and 1.0.0)?

Thanks!

- Robin

It would really be great if the ElasticSearch team would take over this plugin and keep it updated. We use this plugin at Nextdoor and it forces us to stay a few revisions behind on ES to ensure plugin compatibility.

Hi Matt,

Same feelings here. It would definitely make ES more stable in noisy environments like AWS or other Cloud providers.

Best regards,

First of all I need to mention that there is now a good alternative to the zookeeper plugin. Many users of elasticsearch are using dedicated masters setup, which is not more complex than zookeeper setup but provides pretty reliable system. So, I would say it's a good solution definitely worth considering. But, if you still prefer to use zookeeper, I just want to let you know that I have updated my private repo (https://github.com/imotov/elasticsearch-zookeeper) to work with elasticsearch 0.90.12 and 1.0.1. I don't like forks, but since I am no longer with Sonian and I am not sure who is going to maintain zookeeper there, a fork will probably have to do for now until we find a better solution. 

Igor

Igor,
  Excellent to hear back from you on this issue! I actually forked the elasticsearch-zookeeper repo so that we could try to take over doing some work on it and getting it running. I may just pull your changes into our repo and see how it works. If its not difficult in an ongoing basis, we may continue to provide some updates.

  On a side note, where are you at now?

I havn't done any work to debug this ... but the initial unit tests fail from your branch: https://travis-ci.org/diranged/elasticsearch-zookeeper/jobs/20738580

Try running build on 1.0 or 0.90 branch. Master is based on 1.1, which is not released yet. So, it uses snapshot 1.1.0-SNAPSHOT, which is not available from any repository: 

[ERROR] Failed to execute goal on project elasticsearch-zookeeper: Could not resolve dependencies for project com.sonian:elasticsearch-zookeeper:jar:1.1.0-SNAPSHOT: Could not find artifact org.elasticsearch:elasticsearch:jar:1.1.0-SNAPSHOT in sonatype-snapshots (https://oss.sonatype.org/content/repositories/snapshots/) -> [Help 1]

Ah you're right, I merged in those branches to our repo and it looks good: 


We'll be testing this code ASAP. Thank you.

In the long term, what do you think the likelihood of the ElasticSearch team taking ownership of the plugin is? Its highly valuable. We're a big Zookeeper shop here and we've been using this in multiple ElasticSearch farms for almost 2 years now in live production.

I would day it's unlikely to happen in the foreseeable future.

Huge thanks for this Igor! I just tested this on my local instance and it worked on the first try with ES 1.0.0. We are rolling out many ES clusters in our prod environment and this will integrate nicely with our existing ZK cluster. We're mostly a java house here so we might be able to contribute back (time permitting) if you don't mind maintaining the fork.

P.S. Also Hi Matt :) I interviewed with you about 6 months ago. Small world.

Mike,
  :) Small world indeed. Hope things are going well for you at the new place -- but if they aren't, send me an email! :)

Igor,
  Who would we need to petition over at ElasticSearch to vote for priority on this plugin? Its incredibly useful, and makes our clusters super flexible running in the cloud. I'd be happy to give Kevin a hard time, if he's opposed to making this a fully supported plugin. ElasticSearch+Zookeeper = one of our most reliable and easily scaled services in the cloud.
