Cassandra nodes on EC2 in two different regions not communicating
Hi All,
I am trying to configure a cassandra cluster of 2 nodes in different
regions of amazon ec2.
Nodes are running fine but when i try nodetool command with ring option i
get single node.
And both the nodes are able to ping each other, telnet each other. Not
able to figure out what is the problem.
Plz help
Thanks,
Himanshi Sharma

Are you running nodetool on the host, or on a remote machine?
If local, does "netstat -n" show that you are listening on the JMX port?
If remote, have you added the JMX port to your security group?

Re: Cassandra nodes on EC2 in two different regions not communicating
Are you sure you actually re-built Cassandra after making those source
code changes? I believe "Cannot assign requested address" is the error
you
get with the official Cassandra because the external IP address is
not the actual address of an adapter. The patches change the code
so that it listens on all interfaces (so it should not actually be
requesting a specific address)

Re: Cassandra nodes on EC2 in two different regions not communicating
Posted by Himanshi Sharma <hi...@tcs.com>.
Hello All,
My problem with Cassandra across region is solved. Thanks to Milind and
Peter.
I was editing the Source, the two files MessagingService.java and
OutboundTcpConnection.java correctly and even was able to build it
successfully
by referring the patch on
http://www.mail-archive.com/user@cassandra.apache.org/msg05692.html.
The problem was with the cassandra.yaml.
In rpc_address filed, private ip should be used and in listen_address it
should be public. I was trying with public ip in both the fields as well
as by keeping both blank.
Regards,
Himanshi Sharma

Re: Cassandra nodes on EC2 in two different regions not communicating
Posted by Peter Fales <Pe...@alcatel-lucent.com>.
Are you sure you actually re-built Cassandra after making those source
code changes? I believe "Cannot assign requested address" is the error you
get with the official Cassandra because the external IP address is
not the actual address of an adapter. The patches change the code
so that it listens on all interfaces (so it should not actually be
requesting a specific address)

It's pretty easy to do if you're willing/able to make some small changes
to the Cassandra code. Is that an option?
