Carl Yeksigian commented on CASSANDRA-10584:
--------------------------------------------
Yeah, I didn't notice that there was feedback on the dtest; my fault. I'll make
sure to address.

> I think this may be a regression introduced w/ [CASSANDRA-9602]. Starting
> with C* 3.0.0-rc2 an error is returned when querying a keyspace with
> {{SimpleTopologyStrategy}} using EACH_QUORUM CL:
> {noformat}
> cqlsh> create keyspace test with replication = {'class': 'SimpleStrategy',
> 'replication_factor': 1};
> cqlsh> create table test.test (k int PRIMARY KEY, i int);
> cqlsh> consistency EACH_QUORUM;
> Consistency level set to EACH_QUORUM.
> cqlsh> select * from test.test;
> ServerError: <ErrorMessage code=0000 [Server error]
> message="java.lang.ClassCastException:
> org.apache.cassandra.locator.SimpleStrategy cannot be cast to
> org.apache.cassandra.locator.NetworkTopologyStrategy">
> {noformat}
> The exception yielded in the system logs:
