Could it be that it is because I have an installation of apache and tomcat
in the host that I've installed Nutch and it cannot determine whether
'localhost' points to the apache or tomcat? Or does it matter anyway?
I have both servers(apache and tomcat) listening on the default port# which
is 80 and 8080.

I have checked and confirmed that the hosts I'm trying to fetch are
actually accessible (ping requests and loading the site itself). However, I
still get the same error.
Any other alternatives?
