Good to know it works as I well. Thanks for sharing. From: yinghua hu [mailto:[email protected]] Sent: Friday, November 09, 2012 7:48 PM To: [email protected] Subject: Re: error running pi program
Hi, Ted and Andy I tried both internal and external hostnames. They both worked. But I will elect external host name since this way I can browsing the hdfs file structure and other information from a computer not in the cluster. Thanks!

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, AK47 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.
