							 Hi,  I have a 3 node NiFi cluster in the production environment. it has been observed that all the nodes are disconnected from nifi-cluster and all nodes are in running state.  Below are logged.  018-07-05 00:30:19,650 ERROR [Site-to-Site Worker Thread-90476] o.a.nifi.remote.SocketRemoteSiteListener Unable to communicate with remote instance Peer[url=<>] (SocketFlowFileServerProtocol[CommsID=9f090b3e-f5cd-4dae-b893-ef3ba983afef]) due to org.apache.nifi.cluster.exception.NoClusterCoordinatorException: No node has yet been elected Cluster Coordinator.

							 Hello,  I have NiFi Cluster of 2 Nodes, I am using NiFI REST API call to create process group, instantiation of templates, enabling and running processors etc. Sometimes all calls are working fine but randomly getting conflict in any one of the HTTP Call, for the calls which are failing getting 409 in response. It was working fine with Standalone NiFi.  Thanks in advance  Dilip

							 NiFi UI becomes very slow i.e unresponsive all calls take 2-5 min or sometimes does not respond.  My flow.xml.gz file size is 20 MB when it is compressed and 260 MB uncompressed size.  System Configurations: Allocated 20 GB Heap Memory and 8 Cores.
