Received this error:

java.net.BindException: Can't assign requested address: Service 'sparkDriver' failed after 16 retries

Luckily, I found this stackoverflow post, listing instructions:

run hostname

check if the output is present in /etc/hosts

assuming hostname returned potato, you should have in /etc/hosts a line like this:

127.0.0.1 potato

run the java code again, and it should pass
