@pkusnail the zookeeper plugin was created when the existing zen discovery was very flakey and prone to split-brains. This project was already unnecessary in v1.x time-frame, but I updated it to v1.0 enable users to upgrade before switching to zen discovery. Since then a lot of effort went into improving resiliency of elasticsearch. In the current state a properly configured elasticsearch v2.x cluster is much less likely to encounter resiliency problems than v0.90 or v1.0.0 with this plugin. Updating this plugin to v2.3 would require a lot of time that I don't currently have, and considering the current state of zen discovery I don't think creating another discovery plugin would be worth the effort. If you are experiencing split-brains with 2.x branch, it is most likely caused by improper configuration. If this is the case, please, reconfigure your cluster using 3 dedicated master node setup described in the link above and if you are still experiencing issues, don't hesitate to reach out on Elasticsearch support forum with the description of the problem. |
Not sure it that's all that is needed, but all tests are green...
