Can you try the nightly here https://builds.apache.org/job/Cassandra-0.8/ Hope that helps. ----------------- Aaron Morton Freelance Cassandra Developer @aaronmorton http://www.thelastpickle.com On 17 Jun 2011, at 20:52, Vivek Mishra wrote: Thanks Aaron.

I specify the host(s) and keyspace I want to connect to. Alternately, I specify the host(s) and create the keyspace if the one I would like to use doesn't exist (new cluster for example). At no point do I use yaml file with my client code.... The conf/cassandra.yaml is there to tell the cassandra server how to behave / operate when it starts ... -sd On Fri, Jun 17, 2011 at 9:55 AM, Vivek Mishra <vivek.mis...@impetus.co.in<mailto:vivek.mis...@impetus.co.in>> wrote: I have a query: I have my Cassandra server running on my local machine and it has loaded Cassandra specific settings from apache-cassandra-0.8.0-src/apache-cassandra-0.8.0-src/conf/cassandra.y aml Now If I am writing a java program to connect to this server why do I need to provide a new Cassandra.yaml file again? Even if server is already up and running Even if I can create keyspaces, columnfamilies programmatically? Isn't it some type of redundancy? Might be my query is a bit irrelevant. -Vivek ________________________________ Write to us for a Free Gold Pass to the Cloud Computing Expo, NYC to attend a live session by Head of Impetus Labs on 'Secrets of Building a Cloud Vendor Agnostic PetaByte Scale Real-time Secure Web Application on the Cloud '.
