> Collection Deletions for Dropped Columns in 2.1/3.0 mixed-mode can delete rows
> ------------------------------------------------------------------------------
>
> 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.
