Sylvain Lebresne updated CASSANDRA-10254:
-----------------------------------------
Since Version: (was: 2.1.9)
> 3.0 paging states are incompatible with pre-3.0 nodes
> -----------------------------------------------------
>
> Key: CASSANDRA-10254
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10254
> Project: Cassandra
> Issue Type: Bug
> Reporter: Blake Eggleston
> Fix For: 3.0.0 rc1
>
>
> When running the upgrade dtest {{TestCQL.static_columns_with_distinct_test}},
> the client appears to be passing in an invalid paging state (no cell name).
> Instead of catching the problem in validation and returning an error to the
> client, the select statement tries to run it, causing this exception:
> {noformat}
> ERROR QueryMessage.java:135 - Unexpected error during query
> java.lang.ClassCastException:
> org.apache.cassandra.db.composites.Composites$EmptyComposite cannot be cast
