Use cqlsh Instead
The Cassandra CLI is a holdover from the pre-CQL Thrift API. You should migrate to cqlsh, which supports everything you could do from the CLI.
Uprading and wondering how your Thrift data maps to CQL? See these three articles:
- CQL for Cassandra experts
- A thrift to CQL upgrade guide
- Does CQL support dynamic columns and wide rows?
The CLI was formally deprecated starting with Cassandra 2.1 and removed in 3.0.
