rails g cassandra_migrations create_sample_tbl hangs

[soonya]

Facing an issue where the rails generation of the create table script does not work. Cassandra is running. The rails generation ruby process has an established connection and just stays there. Using the default datastax 3.4 cassandra config. Using the default cassandra.yml for cassandra_migrations.

Stack trace on interruption is:
