[RFC] Deploy CDH4 on a cluseter
Hi all,
When i deploy CDH4 on a cluster the doc,
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/4.2.0/CDH4-Installation-Guide/cdh4ig_topic_10.html,
says i have to write IP addresses and FQDN into /etc/hosts.
I am not sure how to get FQDN of each PC? Could anyone give
me some suggestions? Thanks in advance.

Harry,
It doesn't have to be a proper, fully qualified name. Sometimes hosts don't even have one. It just has to match exactly what `hostname` returns, because that's what each node will use to identify itself.
Also, only servers that will actually be part of the cluster need to be in /etc/hosts. Clients can still access the DFS and submit jobs without being explicitly listed.
Regards,
Marcos
