I can open hive but I can't open the WebUI. Above are my files. What is the wrong?

Hi,

Can you explain the issue in brief..

1. what is the error you are seeing while opening the UI?

2. was this accessible earlier?

3. Please attach the screenshot of the error/exception you are seeing.

4. What is the CDH version.

1. I can't open Hive WebUI. It can't connect to the Hive website. It shows "ERR_CONNECTION_REFUSED".

2. No, it always can't connect to the website.

3. There is no other message about it.

4. I have used command line, "hadoop version". There is no information about CDH version.

All codes are below.
