Final answer:
To migrate a table to a Cassandra column family, Sqoop is the correct tool, allowing data transfer from relational databases to Hadoop and then into Cassandra.
Step-by-step explanation:
The question concerns the process of migrating a table to a Cassandra column family. To accomplish this migration, one typically uses specialized tools designed for data transfer between different database systems. The correct tool to migrate a table to a Cassandra column family is Sqoop. Sqoop is a tool designed to transfer data between Hadoop and relational databases. You can use Sqoop to import data from a relational database into Cassandra by first moving the data into Hadoop and then into Cassandra. DataStax also provides tools to assist with the migration but is more focused on managing and scaling Cassandra deployments rather than data import/export itself.
