In the hosts file, it has 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 When running hostname -f, it shows localhost. Will it be ok, or need to use the fully.qualified.domain.name From: m...@gopivotal.com Date: Wed, 2 Apr 2014 17:06:52 +0800 Subject: Re: DNS pre request for hadoop install To: user@hadoop.apache.org
In your /etc/hosts file. Change it to something like below: 127.0.0.1 localhost.localdomain localhost then run hostname -f and see what's the output.

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. alex -- Cheers -MJ
