Newbie question about connecting to a cassandra server from another server using Fauna
Hi I'm trying to create a connection to a server running cassandra doing this:
compass = Cassandra.new('Compas', servers="223.798.456.123:9160")
But once I try to get some data I realize that there's no connection, any ideas?? I'm I missing something ?
Thanks

I've found the solution, thanks for the help, I needed to change the addresses on the storage-conf.xml both ListenAddress and ThriftAddress to the address of the server itself. Sorry about the snippet being incomplete btw

It would help if you give us more context. The code snippet you've
given us is incomplete and not very helpful.

Re: Newbie question about connecting to a cassandra server from another server using Fauna
Posted by Alberto Velandia <be...@gmail.com>.
Hi I've successfully managed to connect to the server through the cassandra-cli command but still no luck on doing it from Fauna, I'm running cassandra 0.6.8 and I did the usual require 'cassandra'
I've changed the ThriftAddress on the storage-conf.xml to the IP address of the server itself, do I need to change anything else?
Thanks once again

You can run the cassandra-cli from any machine. If you run it from the same machine as your ruby code it's a reliable way to check you can connect to the cluster.
ok, next set of questions....
- what version of cassandra are you using ? Is it 0.7?
- what require did you run ? was it require 'cassandra/0.7' ? see the Usage section https://github.com/fauna/cassandra for details.
Cassandra 0.7 defaults to frames transport, 0.6 does not.

Try calling a function like keyspaces(), it should return a list of the keyspaces in your cluster and is a good way to test things are connected.
If there is still no joy check you can connect to your cluster using the cassandra-cli command line app located in cassandra/bin

What function are you calling to get data and what is the error ?
Try calling a function like keyspaces(), it should return a list of the keyspaces in your cluster and is a good way to test things are connected.
If there is still no joy check you can connect to your cluster using the cassandra-cli command line app located in cassandra/bin
