> I am using Nifi 1.11.3 with external Zookeeper 5.3.6. Able to start the Nifi in a cluster mode. When I made complete ZK down, Nifi throwing bellow error and never join with the cluster. I need to restart the Nifi each node to to form cluster back again. Could you please help here ? I think for the production system restarting is not a good option I feel. Tried to increase zookeeper timeout to high values but didn't worked.
