             Summary: Handle zero index searchers in StorageProxy#estimateResultRowsPerRange()
                 Key: CASSANDRA-7741
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7741
             Project: Cassandra
          Issue Type: Bug
            Reporter: Aleksey Yeschenko
            Assignee: Tyler Hobbs
             Fix For: 2.1 rc6


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.
