Hi! What correct config for 6 nodes in 2 AZones (3in 1az+3 in 2az) with embedded ZK (i know that better for use external ZK ) 1) In zookeeper.properties: (which servers add to list?) 2 )in nifi.properties => nifi.zookeeper.connect.string= (which servers add to list?) 3) in state-management.xml =>"Connect String" ((which servers add to list?)) already run cluster in 1 AZ with 3 nodes but when added 4th ,5th, 6th node i see error: WARN [main] o.a.nifi.controller.StandardFlowService There is currently no Cluster Coordinator. This often happens upon restart of NiFi when running an embedded ZooKeeper. Will register this node to become the active Cluster Coordinator and will attempt to connect to cluster again
