can not run Apache nifi on Windows

Question

In my current project, I have been using apache nifi for some experiments purpose. When I have configured the first time. The nifi was running perfect (I was able to see the canvas, toolbar on Google Chrome when I typed http://localhost:8080/nifi/ ). But, after restarting my computer once, I am not able to run it.

When I type nifi.0.7.0\bin\run-nifi.bat command, I see the following message on the console.

Could you please advise me what is the problem? and how could I resolve the issue?

and nifi-user.log is Empty.

When I try to call localhost:8080/nifi/, I see the following.

Answer 1

Try to check if the config file have the following key "nifi.sensitive.props.key=" with a value. If it's empty, please set a key like the example "nifi.sensitive.props.key=132134".
