PIG Cassandra - IPs of nodes in a ring
Hi,
I got a cluster with seven Cassandra nodes. The ring is formed using the
private ips of each of the nodes. The rpc_address of the nodes is set to
private and listen_address of the nodes set to public mainly to facilitate
cross data centre ring. When I ring the nodes, it shows all nodes are up
pointing to private ip.
However when I setup Hadoop/PIG and try to run a PIG script, I get an
exception like java.io.IOException: failed connecting to all endpoints
<ip1>, <ip2>. The ip1 and ip2 are the public ips of nodes part of the ring.
Any suggestion on why it is looking for public ip when the rpc_addr of nodes
and ring is pointing to private ips.
Regards,
badri

Hi Aaron,
The issue was connecting from PIG. For now we have moved to using public ip
for both listen and rpc addreses so that we can continue with our PIG jobs.
We are good for now.
However would like to know whether this sort of configuration supported by
Cassandra in future.
Thanks,
badri

People have been using that sort of configuration in EC2 deployments to run
the listen_address through a VPN and rpc_address on the private IP.
Are you still having troubles connecting ?

Anyone have any thoughts on this thread - about configuring cassandra with a different ip for listen address and rpc address?
moving this to the cassandra user list as it more involves cassandra configuration at this point.

Where are you running the pig script from - your local machine or one of the
nodes in the cluster or ? I would think it wouldn't matter which address
you use, but what interface it's using. So if the internal and public
address are both using the same interface, then you should be able to
connect to cassandra from your local machine using the public address.
That's what I do with EC2. I use the internal address to connect when I'm
connecting within the region and the public address when I'm connecting from
my local machine.
I've never done a different address for rpc_address and listen_address for
that configuration, so there might be peculiarities there that I wouldn't
have seen.

Where are you running the pig script from - your local machine or one of the nodes in the cluster or ? I would think it wouldn't matter which address you use, but what interface it's using. So if the internal and public address are both using the same interface, then you should be able to connect to cassandra from your local machine using the public address. That's what I do with EC2. I use the internal address to connect when I'm connecting within the region and the public address when I'm connecting from my local machine.
I've never done a different address for rpc_address and listen_address for that configuration, so there might be peculiarities there that I wouldn't have seen.
