cqlsh in Cassandra 2.1.0 uses the DataStax python driver. The
"cassandra.metadata" module is provided by this package. By default it uses
the driver from an archive included in the Cassandra distribution
(.../lib/cassandra-driver-internal-only-2.1.0.zip).

See /usr/local/apache-cassandra-2.1.0/bin/cqlsh for how everything gets
setup -- it's possible your wrapper or environment are not playing well
with that.

Also note that "9160" will not apply anymore since this driver uses the
native protocol (9042).
