I am trying to set up HOSTNAME to a machine , but I am unable to find the HOSTNAME field in the /etc/sysconfig/network file

all I can see is this below 

# Generated by anaconda
NETWORKING=yes
NTPSERVERARGS=iburst

Can anyone let me know how can I change the HOSTNAME in this scenario ?

There is a utility available in RHEL to permanently set the hostname:

sudo hostnamectl set-hostname newhostname

Alternatively on RHEL 7 you can simply edit (or create if needed) the file /etc/hostname and add the desired hostname as the only content in the file.

I believe the method you are using is only applicable to RHEL 6 and earlier. If that applies to you, then simply add a hostname field in the format below to that file and reboot:

HOSTNAME=newhostname
