Update for 2020th: DataStax provides a special tool called DSBulk for loading and unloading of data from Cassandra (starting with Cassandra 2.1), and DSE (starting with DSE 4.7/4.8). In simplest case, the command line looks as following:

dsbulk unload -k keyspace -t table -url path_to_unload

DSBulk is heavily optimized for loading/unloading operations, and has a lot of options, including import/export from/to compressed files, providing the custom queries, etc.

There is a series of blog posts about DSBulk, that could provide more information & examples: 1, 2, 3, 4, 5, 6
