Rajesh, You’ll need to look at the following log files to see what the actual cause of the issue is:
* $NIFI_HOME/logs/nifi-bootstrap.log * $NIFI_HOME/logs/nifi-app.log Please share those contents (redacting sensitive information if necessary) if you need further help. The stacktrace should clearly explain the issue though, so hopefully this solves your problem.
