      Description

      Similar to CASSANDRA-14568, if a 2.1 node sends a response to a 3.0 node containing a deletion for a dropped collection column, instead of deleting the collection, we will delete the row containing the collection.

       

      This is an admittedly unlikely cluster state but, during such a state, a great deal of data loss could happen.
