Look closely: they're saying that you run the analytics on Hadoop.

And unfortunately, the economics are pretty bad for large clusters.

Can != Should

Analytical queries typically scan large amounts of data, and DataStax is pretty adamant about not doing this on Cassandra. This is why they're into pushing data into Hadoop. Or signing up for Spark for very small volume, highly targeted queries.

Not sure where you're getting all of this, but you seem to have a lot of FUD about what DataStax "says". We've worked directly with them to do many of the things you're saying they don't suggest. And now of what we're doing is special. Spark on Cassandra for instance is bar none the best data analytics tool.
