[CDH4][RFC] Deploy CDH4 on a cluster

[harryxiyou]

Hi all,

I deploy CDH4 on a cluster, which, in fact, i just wanna deploy
HDFS on this cluster. The cluster is made up of 4 pcs. One of
them is namenode and other ones are datanode. I deploy them as
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/4.2.0/CDH4-Installation-Guide/cdh4ig_topic_11_2.html
says. Howerver, i cannot build this HDFS cluster. My key steps
are like following.

1, Install Ubuntu 12.04 (Precise) for 4 pcs.
2, Install java-6-sun-1.6.0.06.
3, Configure network names. (4 pcs are under a local area network).
4, Deploy HDFS on this cluster as
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/4.2.0/CDH4-Installation-Guide/cdh4ig_topic_11_2.html
says.

At last, after i format the namenode, it seems the namenode
has no connections with other datanodes.
Could anyone have some more clear blogs for deploying HDFS on a
cluster or some suggestions for me?
Thanks in advance ;-)
