Hi – We are exploring nifi for our workflow management, I have a cluster setup with 3 nodes. One as master and rest as slaves.
I see following error when I try to access the nifi workflow webpage. 2015-09-29 22:46:13,263 WARN [NiFi Web Server-23] o.a.n.c.m.impl.HttpRequestReplicatorImpl Node request for [id=7481fca5-930c-4d4b-84a3-66cc62b4e2d3, apiAddress=localhost, apiPort=8080, socketAddress=localhost, socketPort=3002] encountered exception: java.util.concurrent.ExecutionException: com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused 2015-09-29 22:46:13,263 WARN [NiFi Web Server-23] o.a.n.c.m.impl.HttpRequestReplicatorImpl Node request for [id=0abd8295-34a3-4bf7-ab06-1b6b94014740, apiAddress=localhost, apiPort=8080, socketAddress=10.233.2.42, socketPort=3002] encountered exception: java.util.concurrent.ExecutionException: com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused 2015-09-29 22:46:13,264 INFO [NiFi Web Server-23] o.a.n.c.m.e.NoConnectedNodesException org.apache.nifi.cluster.manager.exception.NoResponseFromNodesException: No nodes were able to process this request..
