Description

This may be related to CASSANDRA-6738, although the stacktraces show a pretty different path:

ERROR 23:13:17 Error occurred during processing of message.

To reproduce, you can run this pycassa test:

python setup.py nosetests -w tests/test_autopacking.py:TestComposites.test_static_composite_get_partial_composite

The comparator is:

CompositeType(LongType, IntegerType, ReversedType(TimeUUIDType),  LexicalUUIDType, AsciiType, UTF8Type, BytesType)

The insert that triggers the error only uses the first two components of the comparator:

cf.insert('key3', {(123123, 1): 'val'})
