> 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';
