Re: Newbie question about connecting to a cassandra server from another server using Fauna
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/binAaronOn 07 Dec, 2010,at 08:46 AM, Alberto Velandia betovelan...@gmail.com wrote: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??

Re: Newbie question about connecting to a cassandra server from another server using Fauna
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 sectionhttps://github.com/fauna/cassandrafor details.Cassandra 0.7 defaults to frames transport, 0.6 does not.AaronOn 07 Dec, 2010,at 09:07 AM, Alberto Velandia betovelan...@gmail.com wrote:I've tried the keyspaces() function and got this on return:compass.keyspaces()CassandraThrift::Cassandra::Client::TransportException: CassandraThrift::Cassandra::Client::TransportException from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift-0.2.0.4/lib/thrift/transport/socket.rb:53:in `rescue in open' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift-0.2.0.4/lib/thrift/transport/socket.rb:36:in `open' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift-0.2.0.4/lib/thrift/transport/buffered_transport.rb:37:in `open' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift_client-0.5.0/lib/thrift_client/connection/socket.rb:11:in `connect!' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift_client-0.5.0/lib/thrift_client/abstract_thrift_client.rb:82:in `connect!' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift_client-0.5.0/lib/thrift_client/abstract_thrift_client.rb:110:in `handled_proxy' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/thrift_client-0.5.0/lib/thrift_client/abstract_thrift_client.rb:57:in `get_string_property' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/cassandra-0.8.2/lib/cassandra/cassandra.rb:302:in `all_nodes' from /home/compass/.rvm/gems/ruby-19.2...@rails3/gems/cassandra-0.8.2/lib/cassandra/cassandra.rb:285:in `reconnect!' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/cassandra-0.8.2/lib/cassandra/cassandra.rb:280:in `client' from /home/compass/.rvm/gems/ruby-1.9.2...@rails3/gems/cassandra-0.8.2/lib/cassandra/cassandra.rb:86:in `keyspaces' from (irb):4 from /home/compass/.rvm/rubies/ruby-1.9.2-p0/bin/irb:16:in `main'about the cassandra-cli, should I run the command on the server from which I'm trying to connect?Thanks for the helpOn Dec 6, 2010, at 2:52 PM, Aaron Morton wrote: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/binAaronOn 07 Dec, 2010,at 08:46 AM, Alberto Velandia betovelan...@gmail.com wrote: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??

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?
