Subject Re: IP address resolution in MultiDC setup
Date Mon, 25 Apr 2011 13:30:23 GMT
scrap the last mail, just finished reading Amazon ec2 resource policy.

@milind when deploying cassandra across multiple dcs using your patch, is it
possible to have internal network of nodes in each data center talking over
private ip?
then I assume the node with public ip will act as co-ordinator. If it goes
down the link between data centers will be down?

Thanks
pankaj
