Andy Tolbert created CASSANDRA-10584:
----------------------------------------
Summary: reads with EACH_QUORUM on keyspace with
SimpleTopologyStrategy throw a ClassCastException
Key: CASSANDRA-10584
URL: https://issues.apache.org/jira/browse/CASSANDRA-10584
Project: Cassandra
Issue Type: Bug
Reporter: Andy Tolbert
Priority: Minor
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:
{noformat}
ERROR [SharedPool-Worker-1] 2015-10-23 13:02:15,405 ErrorMessage.java:336 -
Unexpected exception during request
java.lang.ClassCastException: org.apache.cassandra.locator.SimpleStrategy
cannot be cast to org.apache.cassandra.locator.NetworkTopologyStrategy

{noformat}
On 3.0.0-rc1 we get an invalid query error back instead (as expected with prior
to [CASSANDRA-9602]):
{noformat}
InvalidRequest: code=2200 [Invalid query] message="EACH_QUORUM ConsistencyLevel
is only supported for writes"
