[RFC] Deploy CDH4 on a cluster

[harryxiyou]

Hi all,

When i deploy CDH4 on a cluster, i configure network
names like http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/4.2.0/CDH4-Installation-Guide/cdh4ig_topic_11_1.html.

My cluster has 4 pcs, which one is namenode and
other 3 ones are datanode. They are under local area
network which i use NAT technology to let them surf
the Internet. After the command 'host -v -t A `hostname`' is
executed, i get following messages

$ host -v -t A `hostname`
Trying "ubuntu2"
Host ubuntu2 not found: 3(NXDOMAIN)
Received 100 bytes from 202.117.128.2#53 in 65 ms

I find the output messages are not right. Actually,
'202.117.128.2' is our DNS server. Could anyone give me some
suggestions?
