Cannot create CompositeType using pycassa (worked in 0.8.x)
-----------------------------------------------------------

                 Key: CASSANDRA-3401
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3401
             Project: Cassandra
          Issue Type: Bug
          Components: Core, Drivers
    Affects Versions: 1.0.0
            Reporter: Justin Plock


Using pycassa 1.2.1 against Cassandra 0.8.x, this code worked fine:
{code}
key_field_comparator = pycassa.CompositeType(pycassa.TimeUUIDType(), pycassa.UTF8Type())
value_key_comparator = pycassa.CompositeType(pycassa.UTF8Type(), pycassa.TimeUUIDType())
SYSTEM_MANAGER.create_column_family('Indexes', 'Items', comparator_type=value_key_comparator,
default_validation_class=pycassa.TIME_UUID_TYPE, key_validation_class=key_field_comparator)
{code}
However, against Cassandra 1.0, this same code will now hang my python script indefinitely.
After killing the program, Cassandra will crash and will throw this exception:
{code:javascript}
Exception encountered during startup: Could not inflate CFMetaData for {
