You could see more from http://docs.datastax.com/en/cql/3.1/cql/cql_reference/create_table_r.html

To support future capabilities, a column definition of a user-defined or tuple type requires the frozen keyword. Cassandra serializes a frozen value having multiple components into a single value. For examples and usage information, see "Using a user-defined type", "Tuple type", and Collection type.

Note: Cassandra 2.1.0 to 2.1.2 requires using frozen for tuples:

frozen <tuple <int, tuple<text, double>>>

Cassandra 2.1.3+ does not require this keyword.
