Subject [jira] [Created] (CASSANDRA-10584) reads with EACH_QUORUM on keyspace with SimpleTopologyStrategy throw a ClassCastException
Date Fri, 23 Oct 2015 18:07:27 GMT
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

{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"
