Tam, The error message in the log:
2020-10-11 12:13:27,609 ERROR [NiFi logging handler] org.apache.nifi.StdErr Failed to start web server: Failed to bind to 0.0.0.0/0.0.0.0:8080 Indicates that there is already another application (or another instance of nifi) running on port 8080. So you’ll need to shut down that application or change the conf/nifi.properties file to listen in a different port.

I attach the information in the log file in this email. Could you please help to let me know what I did wrong here? Thanks for your help, Tam <PostMessage_20201011.txt>
