Hello Ted,

 

Thanks yours below. I do run hadoop on EC2 as well. And I use internal host-addresses ($hostname –f) for configuration of core-site/hdfs-site/slaves/master files.

 

The only time I switch to external address i.e. ec2-……  is when I want to access my nodes vie the web,i.e. external address  - ec2……:50070 or ec2……:50030

 

Rgds,

yinghua,

 

One other thing to note here is that on EC2 computer are given two hostnames, one internal and one external, you need to use the external.  These host names are listed in the ec2 configuration pane on the AWS management console.
