Hi, I have few doubts regarding NiFi cluster.
1) In case we schedule a processor to run on only one node using 'On primary node' as 'Scheduling Strategy' then is the processor still configured on all nodes? If yes, then does then which is the actual step in processor lief cycle that takes place on the primary node? 2) I am starting to look into 'State Management' and do not see any Zookeeper quorum specified in default 'state-management.xml' and also 'nifi.state.management.embedded.zookeeper.start' is set as 'false' under 'nifi.properties' file. Do we have to configure a Zookeeper for cluster and how is Zookeepr being used? 3) All the nodes in the cluster work on the data flow. What happens to the data if in case the node processing it goes down? Does the NCM takes care of sending the failed data to other nodes for processing as the nodes do not communicate with each other. Appreciate if someone can guide for any documentation apart from those available under 'Administrator Guide' for NiFi clustering. Thanks & Regards, Sudeep
