>                 Key: CASSANDRA-14749
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14749
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>            Reporter: Benedict
>            Assignee: Benedict
>            Priority: Major
>             Fix For: 3.0.18

>
> 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.
