Listen tcp 127.0.0.1:8080: bind: address already in use

I am trying to ingest data into my localhost by using bulk loader.
I have run the below command in my terminal

dgraph bulk -f /home/mouninka_mandadic/Downloads/Dgraph/data.rdf -s /home/mouninka_mandadic/schema1 --ignore_errors

i am facing this error
Connecting to zero at localhost:5080
2021/05/27 14:06:46 listen tcp 127.0.0.1:8080: bind: address already in use

How to resolve this?

It depends, what OS are you using? You have to use some OS tool to find out what program is using that port.
