[I] Coordinator fails to elect leader when zookeeper connection transitions from LOST state to RECONNECTING state (druid)
vimil-saju opened a new issue, #17786:
URL: https://github.com/apache/druid/issues/17786
Please provide a detailed title (e.g. "Broker crashes when using TopN query with Bound filter" instead of just "Broker crashes").
### Affected Version
29.0.0
The Druid version where the problem was encountered.
### Description
We have druid 29.0.0 deployed on a kubernetes cluster. We also have zookeeper installed in the cluster with istio-proxy enabled. When we disabled istio-proxy on the zookeeper pods and restarted zookeeper we noticed that druid coordinators lost leadership and the LeaderLatch did not invoke reset() to create the ephemeral node when the Zookeeper Connection State transitioned from `LOST` to `RECONNECTING`. This caused requests to coordinators to result in 503 errors, because there was no leader. Upon investigating further we found that this issue exists in curator library version 5.5 that druid uses and is fixed in 5.8 version - https://issues.apache.org/jira/browse/CURATOR-724
I think upgrading curator version to 5.8 will fix this issue.
