Answer 1

Try to do ssh to your local system using the IP, in this case:

$ ssh 127.0.0.1

Once you are able to do the ssh successfully. Run the below command to know the list of open ports

~$ lsof -i

look for a listening connector with name: localhost:< PORTNAME > (LISTEN)

copy this < PORTNAME > and replace the existing value of port number in tag of fs.default.name property in your core-site.xml in the hadoop conf folder

save the core-site.xml, this should resolve the issue.
