The more detail you provide the better community members can assist with your question.
Just looking at the screen capture you posted, it appears that you are working with the HDP Sandbox, not a full-scale installation of HDP on a dedicated cluster. You should also post the specific virtualization platform you're using. Perhaps another member of the community will recognize this specific problem with the Sandbox and respond in this thread.
You didn't indicate what version of the HDP Sandbox you installed. If you don't know how to retrieve the version of the Sandbox you've installed, please read through this tutorial:
…and scroll down to the subsection Sandbox Version and follow the instructions there.
You didn't indicate how you installed NiFi, what version you installed or how you determined that the installation was successful. If you didn't install a version and distribution that was designed to work on the HDP Sandbox, your efforts are unlikely to be successful if you are a beginner. Assuming you are fairly new to NiFi, I'd recommend that you start over and you install an appropriate version of the Cloudera DataFlow (CDF) Sandbox for the HDP Sandbox you are using.
NiFi's UI will not be available immediately after you start the service.
The UI will not be available until the child process has finished loading. You can monitor teh progress by tailing the nfii-app.log. Once you see the log line that states:
2021-07-13 19:46:43,855 INFO [main] org.apache.nifi.web.server.JettyServer NiFi has started. The UI is available at the following URLs: 2021-07-13 19:46:43,855 INFO [main] org.apache.nifi.web.server.JettyServer http://127.0.0.1:9090/nifi 2021-07-13 19:46:43,858 INFO [main] org.apache.nifi.BootstrapListener Successfully initiated communication with Bootstrap 2021-07-13 19:46:43,858 INFO [main] org.apache.nifi.NiFi Controller initialization took 44494103250 nanoseconds (44 seconds).
then you should be able to access the NiFi UI provided you can reach that address from your client browser.
