--------------------------------------------
Could not reproduce on latest 2.1.0 on OS X.
[~cfsnyder] can you please check what is the output of {{python -c "from blist
import sortedset"}} on your system?
> cqlsh error when selecting data from a table with nested UDTs
> -------------------------------------------------------------
>
> Key: CASSANDRA-8030
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8030
> Project: Cassandra
> Issue Type: Bug
> Environment: Ubuntu 14.04. Cassandra 2.1.0. Single node.
> Reporter: Cory Snyder
> Labels: cqlsh
> Attachments: example_statements.txt, schema.txt
>
>
> 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:
> {code}
> 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'
> {code}
> 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.
