I have a problem about Nifi Web UI. When I set nifi.web.http.host=luan-ht01, I could not access Nifi Web UI on browsers by public IP, example: http://localhost:8080/nifi/, http://107.113.193.160:8080/nifi. I only could access Nifi Web by host name, example: http://luan-ht01:8080/nifi/ . Do you have any solutions? Thank you very much. I 'm using Nifi 1.9.0.

Ambari version: 2.7.3.0 Ubuntu version: 16.04 When I used Ambari to deploy Hadoop cluster, Ambari created 2 file in apt source.list.d (ambari-hdp-1.list and hdp.list). So they could not run.
