Modifying host monitor port number

If you use NiFi with security enabled, then the Cloudera host monitor port number and the NiFi port number might be the same. That causes problems. So before continuing, you must modify it and then restart the Cloudera Management service.

  1. Go to the Cloudera Manager main dashboard.
  2. Select Cloudera Management Service.
  3. Click Configuration.
  4. Search for the Host Monitor Web UI HTTPS Port configuration value.
  5. If the value is 9091, modify it to 9092 or other free port numbers, and save the configuration.
  6. Restart Cloudera Management Service.
