Stefania commented on CASSANDRA-12582:
--------------------------------------
It's worth noting that the exception I reproduced is actually different that
the one in the ticket description. It seems the exception in the description is
failing to read a static row whilst the exception I reproduced is failing to
read a regular row (a clustering to be exact), I hope the workaround in the
serialization header covers both, but I cannot reproduce the exact exception in
the description.

> After debugging, it appears that a previously dropped static column (weeks
> prior) was the instigator of the issue. As a workaround we added back the
> column, restarted all cassandra processes within the cluster, and the read
> error and corruption exception went away.
> Attached is a script to reproduce with a simple schema.
> Also noteworthy (and shown in the script) is that when in this state,
> compaction silently failed (exit 0) to remove the dropped static columns from
> the "corrupted" sstable.
