------------------------------------------

             Summary: ClassCastException in SelectStatement
                 Key: CASSANDRA-10988
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10988
             Project: Cassandra
          Issue Type: Bug
          Components: CQL
            Reporter: Vassil Hristov


After we've upgraded our cluster to version 2.1.11, we started getting the 
bellow exceptions for some of our queries. Issue seems to be very similar to 
CASSANDRA-7284.

{code:java}
java.lang.ClassCastException: 
org.apache.cassandra.db.composites.Composites$EmptyComposite cannot be cast to
