I am having a doubt. i am in process of implementing kerberos in CDH5 ..
i am using a /etc/hosts file instead of DNS and it looks like .
10.0.0.6 node01.mydomain.com node01
Now my question is
My cluster is running and i am using host name without domain but we have to use FQDN for kerberos congifuration .
so can i keep hadoop configuation same and just use FQDN for kerberos related parameter in hdfs-site.xm .
