----------------------------------------

> Adding columns via ALTER TABLE can generate corrupt sstables
> ------------------------------------------------------------
>
> Key: CASSANDRA-16735
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16735
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Repair, Local/SSTable
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Priority: Normal
>
> This is similar to CASSANDRA-13004 and was caused by CASSANDRA-15899
> Basically the column placeholders introduced in 15899 can get read-repaired in to the memtable and later flushed to disk and in some cases this can conflict with the actual column (if the actual column is a collection for example) and cause CorruptSSTableExceptions.
> Fix is probably to just revert 15899, at least until if and when we find a solution that we can rely on. Will post that + test next week.
