JNA is _not_ necessary to use Cassandra, but the server can perform some operations more efficiently
if JNA is in place.

Not sure what is causing the error you are seeing in the CLI though: those statements appear
to be valid.

See this page:

"Because of licensing issues <>, 
we can't distribute JNA with Cassandra, so you must manually add it to 
the Cassandra lib/ directory or otherwise place it on the classpath."
