Subject [jira] Commented: (HADOOP-2474) Automate EC2 DynDNS setup
Date Tue, 15 Apr 2008 19:38:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589201#action_12589201

Steve Loughran commented on HADOOP-2474:

httpclient can do this in JVM, no need for any extra dependencies; works anywhere that proxies
are not in the way.

 Be aware that dyndns dont like aggressive clients; you should get the current value before
attempting to change it only if different..

> Use the DynDNS webservice (https://www.dyndns.com/developers/specs/syntax.html) to automatically
set up DNS for the EC2 cluster master node. If no DynDNS credentials are set (in hadoop-ec2-env.sh)
then prompt the user to set up DNS manually (the existing behaviour).
