It's probably some sort of config problem.

Is there a way accompolish this in cassandra? Secondary index does

when I query based on indexed value it says "Row does not found".

I am using Cassandra-0.7.8 on cluster of 4 machines. I have uploaded some files

I wanted to perform SQL operations such as BETWEEN, ORDER BY with ASC/DSC order

It looks it is know issue with Cassandra-0.8.4. So either I have to wait till

that.

At a guess I would say there are no nodes listed in the Hadoop JobConf.

This is regarding multi-node cluster configuration doubt.
I have configured 3 nodes of cluster using Cassandra-0.8.4 and getting error

What is rpc_address set to in cassandra.yaml?
Try setting these to 0.0.0.0 to be sure it's listening to external traffic.
