Description

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:

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.
