Description

CASSANDRA-7525 has broken Thrift's ability to filter based on arbitrary columns, even those without a secondary index defined.

Two of the thrift tests are broken because of this:

• https://github.com/apache/cassandra/blob/cassandra-2.1.0/test/system/test_thrift_server.py#L1982
• https://github.com/apache/cassandra/blob/cassandra-2.1.0/test/system/test_thrift_server.py#L1605

Both trigger this assert: https://github.com/apache/cassandra/blob/cassandra-2.1.0/src/java/org/apache/cassandra/service/StorageProxy.java#L1457

This is not a path reachable via CQL3 yet (until/if we further extend ALLOW FILTERING power), but it can be legally reached via Thrift, and should handle the possibility.

• is broken by: CASSANDRA-7525 Querying by multiple secondary indexes gives java.lang.IllegalArgumentException on some cases
• relates to: CASSANDRA-5687 Move C* Python Thrift tests into dtests
