I have installed HDF 2.1.2 with 3 node Nifi 1.1 cluster and I am trying to configure controller service in it. I created a simple ExecuteHQL processor which depends on ThriftConnectionPool controller service.
I dragged ExecuteProcessor on canvas and as soon as I clicked on gear icon for configuring controller service , it throws runtime exception in log.
Attempting request for (anonymous) GET http://<hostname>:9090/nifi-api/flow/process-groups/83490f62-015c-1000-0000-00004da8f033/controller-
HTTP 500 Internal Server Error
I had duplicate controller service jar - one actual and another symlink which was causing issue.
