[jira] Commented: (HADOOP-2776) Web interface uses internal hostnames on EC2

    [ https://issues.apache.org/jira/browse/HADOOP-2776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12588020#action_12588020 ] 

Nate Carlson commented on HADOOP-2776:
--------------------------------------

I get by this by setting up nph-proxy (http://www.jmarshall.com/tools/cgiproxy/) on the master Hadoop node, and use that to browse the hosts. Kind of a hack, but works well for me.

>             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).
