if you are using dhcp to set the IP address, you can also use it to set
the hostname (assuming that each system has an individual host entries)

set the following in /etc/sysconfig/network/dhcp (although I think this
is the default)
DHCLIENT_SET_HOSTNAME="yes"

what the above does is turn on the -H option to dhcpcd (see the man for
dhcpcd for the details)

I am always trying to cut the numbers of these files down.  I would say
that unless all of your nodes are unique in multiple ways (which that
should not really be the case for a cluster), I would say try and
consolidate.
