Cassandra wih Hive
You're in luck: DataStax just released Brisk, a Cassandra distribution integrating Hadoop and Hive.
You can look in to WSO2 BAM2 to get an idea about Hive Cassandra integration.
https://svn.wso2.org/repos/wso2/carbon/platform/branches/4.0.0/components/bam2/
You need a Cassandra java storage library.
And here is one https://github.com/dvasilen/Hive-Cassandra
