Subject [jira] Commented: (HADOOP-2474) Automate EC2 DynDNS setup
Date Thu, 17 Apr 2008 19:31:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12590176#action_12590176

Chris K Wensel commented on HADOOP-2474:

then maybe a new command should be added to register a particular cluster master ip against
a given dyndns name..

since there are no internal dependencies on the dyndns name, this would an optional call by
the user.

for example,
> hadoop-ec2 register-name <group-name> <dns-name>

> 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).
