We have been testing Druid environment but getting below errors in druid nodes when any of zookeeper goes down and even if comes back.
org.apache.curator.framework.imps.CuratorFrameworkImpl - Background operation retry gave up
In cluster we have
Machine 1 - zookeeper, RT, Historical
Machine 2 - zookeeper, Historical
Machine 3 - zookeeper, Historical, Indexer, Coordinator
Machine 4 - kafka, Historical
I found similar issues in topic here

At the end discusstion talks about announcer.type to batch. But I suppose that’s default in druid 0.6.146
Any help on this?
