Condition 1- I am using Apache NIFI cluster as docker in ECS and running one external Zookeeper in EC2 instance, everything is working fine.
But I want to maintain high availability for Zookeepers as well therefore
Condition 2- I am using Apache NIFI cluster as docker in ECS and running 2 external Zookeeper in different EC2 instances. When both the Zookeepers are up, everything works fine but the moment I bring down one of the Zookeeper, it results in error dialog saying "Cluster connection- This node is currently not connected to the Cluster. Any modifications to the data flow made here will not replicate across the Cluster". My expectation is, when one Zookeeper goes down, another one should take over so that high availability is maintained. Please suggest what am I doing wrong. I am using docker environment variable for NIFI as- NIFI_ZK_CONNECT_STRING = EC2 instance-1 IP:2181,EC2 instance-2 IP:2181 Note: Zookeeper is running in both the EC2 instances in port 2181
