Web interface uses internal hostnames on EC2
--------------------------------------------
Key: HADOOP-2776
URL: https://issues.apache.org/jira/browse/HADOOP-2776
Project: Hadoop Core
Issue Type: Bug
Components: contrib/ec2
Affects Versions: 0.15.1
Environment: EC2 ami-a324c1ca
Reporter: David Phillips
The web interface, for example http://$MASTER_HOST:50030/machines.jsp, uses
internal hostnames when running on EC2. This makes it impossible to access
from outside EC2.
The slaves file has the public names listed. Resolving a public name inside
EC2 returns the private IP (which would reverse to the internal DNS name).
