Configure Bind

BIND's process is known as named. As such, many of the files refer to "named" instead of "BIND".

On hadoop1, open the named.conf file for editing:

vi /etc/named.conf

Note:

1. acl "trusted": all the host in domain are included here

2. options{indicate the dns server hadoop1 and it is listening to port 53}

3. set the dns failover to secondary dns: hadoop2
