Do you got "hosts: files dns" in your nsswitch.conf?
Otherwise , /etc/hosts won't be used.

# /etc/nsswitch.conf
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
passwd:         compat
group:          compat
