You should change it in both places, and then run /etc/init.d/network
restart to make it effective.

/etc/hosts basically tells your own machine on which IP a certain
domain resolves to. It's a "scaled down DNS server", and normally only
used if you only need to maintain a few hosts on a network.

/etc/sysconfig/network tells your machine what it's actual hostname is.
