I am working on an Apache Cassandra data migration. I have couple of tables which I need to move to the Cassandra column family with data - what is the best way to do this?
I have seen Apache Sqoop, will it help me? If yes, then what are the steps?

There is no silver bullet to migrate data from Oracle (or any RDBMS) to Cassandra. The way your data is modeled in Cassandra is fundamentally different from a relation database schema. Tools might help you to some degree, but you'll first have to create a new data model that will match the way you're going to read and write data into Cassandra. This article gives you a good start with Cassandra data modeling: http://www.datastax.com/dev/blog/basic-rules-of-cassandra-data-modeling
