Hello,
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 ec2-1-2-3-4.compute-1.amazonaws.com) and one node in US-WEST (say
ec2-2-2-3-4.us-west-1.compute.amazonaws.com).
Using Cassandra 0.7.4
The one in east region is the seed node and has the values as:
auto_bootstrap: false
seeds: ec2-1-2-3-4.compute-1.amazonaws.com
listen_address: ec2-1-2-3-4.compute-1.amazonaws.com
rpc_address: 0.0.0.0
The one in west region is non seed and has the values as:
auto_bootstrap: true
seeds: ec2-1-2-3-4.compute-1.amazonaws.com
listen_address: ec2-2-2-3-4.us-west-1.compute.amazonaws.com
rpc_address: 0.0.0.0
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 /2.2.3.4
attempting to connect to /10.170.190.31
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
