Subject EC2 - 2 regions
Date Fri, 18 Mar 2011 15:34:11 GMT

I am trying to setup a cassandra cluster across regions.
For testing I am keeping it simple and just having one node in US-EAST
(say and one node in US-WEST (say
Using Cassandra 0.7.4

The one in east region is the seed node and has the values as:
auto_bootstrap: false

The one in west region is non seed and has the values as:
auto_bootstrap: true

I first fire the seed node (east region instance) and it comes up
without issues.
When I fire the non-seed node (west region instance) it fails after
sometime with the error:

DEBUG 15:09:08,844 Created HHOM instance, registered MBean.

The seed node seems to somewhat acknowledge the non-seed node:
attempting to connect to /
attempting to connect to /

Can you suggest how can I fix it (I did see a few threads on similar
issue but did not really follow the chain)

Thanks, AJ
