Description

The schema that was being used when this error was produced is attached. Whenever I try to select data from the LOAD_BALANCER_SERVICE table after having written data with non-empty sets for either the pools or virtual_servers fields, cqlsh fails with the following exception:

Traceback (most recent call last):
  File "/usr/bin/cqlsh", line 909, in perform_simple_statement
    rows = self.session.execute(statement, trace=self.tracing_enabled)
  File "/usr/share/cassandra/lib/cassandra-driver-internal-only-2.1.0.post.zip/cassandra-driver-2.1.0.post/cassandra/cluster.py", line 1281, in execute
    result = future.result(timeout)
  File "/usr/share/cassandra/lib/cassandra-driver-internal-only-2.1.0.post.zip/cassandra-driver-2.1.0.post/cassandra/cluster.py", line 2772, in result
    raise self._final_exception
TypeError: unhashable type: 'set'

I am, however, able to select the data from the table with the Java Datastax driver. I am also able to select data from the table if both the pools and virtual_servers fields are empty sets.
