David Phillips commented on HADOOP-2474:
----------------------------------------

Updating DynDNS is easy using curl:

DYNDNS_USER=username
DYNDNS_PASS=password

echo "Updating DynDNS"
curl -k "https://$DYNDNS_USER:$DYNDNS_PASS@members.dyndns.org/nic/update?hostname=$MASTER_HOST&myip=$MASTER_IP"
echo

> 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).
