> Key: CASSANDRA-14414
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14414
> Project: Cassandra
> Issue Type: Bug
> Reporter: Ken Hancock
> Priority: Major

> In upgrading from 1.2.18 to 2.0.17, the following exceptions started showing in cassandra log files when the 2.0.17 node is chosen as the coordinator. CL=ALL reads will fail as a result.
> The following ccm script will create a 3-node cassandra cluster and upgrade the 3rd node to cassandra 2.0.17
> {code}
> ccm create -n3 -v1.2.17 test
> ccm start
> ccm node1 cli -v -x "create keyspace test with placement_strategy='org.apache.cassandra.locator.SimpleStrategy' and strategy_options={replication_factor:3}"
> ccm node1 cli -v -x "use test;
> create column family super with column_type = 'Super' and key_validation_class='IntegerType' and comparator = 'IntegerType' and subcomparator = 'IntegerType' and default_validation_class = 'AsciiType'"
> ccm node1 cli -v -x "use test;
> create column family shadow with column_type = 'Super' and key_validation_class='IntegerType' and comparator = 'IntegerType' and subcomparator = 'IntegerType' and default_validation_class = 'AsciiType'"
> ccm node1 cli -v -x "use test;
> set super[1][1][1]='1-1-1';
> set super[1][1][2]='1-1-2';
> set super[1][2][1]='1-2-1';

> The following python uses pycassa to exercise the range_slice Thrift API:

> import pycassa
> from pycassa.pool import ConnectionPool
> from pycassa.columnfamily import ColumnFamily
> from pycassa import ConsistencyLevel
> pool = ConnectionPool('test', server_list=['127.0.0.3:9160'], max_retries=0)
> super = ColumnFamily(pool, 'super')
> print "fails with ClassCastException"
> super.get(1, columns=[1,2], read_consistency_level=ConsistencyLevel.ALL)
> print "fails with RuntimeException: Cannot convert filter to old super column format...""
> super.get(1, column_start=2, column_finish=3, read_consistency_level=ConsistencyLevel.ALL)
> {code}
