I use NiFi 1.24 as a standalone. Today I installed Apache Drill and Apache Zookeeper as a daemon.
Of course, I immediately tested whether everything works again after a reboot. And lo and behold: of course not. I suddenly get the error message in the nifi-bootstrap.log: 2024-03-08 16:10:05,430 INFO [main] org.apache.nifi.bootstrap.Command Launched Apache NiFi with Process ID 8804 2024-03-08 16:10:05,461 INFO [NiFi logging handler] org.apache.nifi.StdOut Listening for transport dt_socket at address: 8000 2024-03-08 16:10:05,785 INFO [NiFi Bootstrap Command Listener] org.apache.nifi.bootstrap.RunNiFi Apache NiFi now running and listening for Bootstrap requests on port 41543 2024-03-08 16:10:09,567 ERROR [NiFi logging handler] org.apache.nifi.StdErr Failed to start web server: javax.servlet.ServletContainerInitializer: com.sun.jersey.server.impl.container.servlet.JerseyServletContainerInitializer Unable to get public no-arg constructor 2024-03-08 16:10:09,567 ERROR [NiFi logging handler] org.apache.nifi.StdErr Shutting down... 2024-03-08 16:10:10,432 INFO [main] org.apache.nifi.bootstrap.RunNiFi NiFi never started. Will not restart NiFi Can anyone tell me what this means? I can't see that any port is used that NiFi needs. And the statement "Unable to get public no-arg constructor" is surprising to me, since NiFi was already working before. But still, I have broken something. But what? -- Kay-Uwe
