How to drop a LISTEN port in CentOS7? the port dose not seem to binding to any process

Question

I would like to drop a port which is currently in state LISTEN.

This is when I type netstat -anp | grep LISTEN | grep 8080.

(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      -  

as you can see, there is no process ID.

I have also tried fuser -n 8080 tcp and fuser 8080/tcp, but those commands print nothing.

How could drop the port safely? - My original plan was find pid and command kill, but is there any safer way to stop a port?

Thanks.

I found out. It was caused by user. If I try with user root. It prints the pid

[iceman ~]$ sudo netstat -anp | grep 8080
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      47950/uni***
