> Key: CASSANDRA-14823
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14823
> Project: Cassandra
> Issue Type: Bug
> Components: Local/SSTable
> Reporter: Blake Eggleston
> Assignee: Blake Eggleston
> Priority: Urgent
> Fix For: 3.0.18, 3.11.4
>
>
> During upgrade from 2.1 to 3.0, reading old sstables in reverse order would
> generate invalid sequences of range tombstone bounds if their range
> tombstones spanned multiple column index blocks. The read fails in different
> ways depending on whether the 2.1 tables were produced by a flush or a
> compaction.
