             Summary: CompoundDenseCellNameType AssertionError and BoundedComposite to CellName ClasCastException
                 Key: CASSANDRA-7990
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7990

            Reporter: Christian Spriegel
            Priority: Minor


I just updated my laptop to Cassandra 2.1 and created a fresh data folder.

When trying to run my automated tests i get a lot these exceptions in the Cassandra log:

{code}

I cannot say what is causing these. So I am posting this as it is for now, hoping somebody already knows what the issue is.

- Currently CQL and thrift is running side by side.
- Many of the CQL tables use compact storage.

I could dig deeper and try to isolate the cause if necessary.
