I am trying to use ambari (hortonwoks) to install hadoop. One step is to
pre-config DNS as manual link below.
http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.1/bk_using_Ambari_book/content/ambari-chap1-5-5.html
Since I am only using internal network, not sure how to config
fully.qualified.domain.name. My hostname -f only shows localhost. And in
/etc/sysconfig/network, it give HOSTNAME=localhost.localdomain
If anyone already get hadoop running, what is the real DNS requests for hadoop.
Any suggestion, thanks a lot.
