> The patch in CASSANDRA-3716 causes some weird issues to arrise when server
> times don't exactly match up (and since the resolution is seconds, it is easy
> to be off by just enough to see it).
> I am seeing a case where during schema propagation .isMarkedForDelete() is
> checked, but the timestamp is a few seconds in the future because the schema
> was sent from a different node. The code then happily tries to interpret the
> value of the column as a String, but it is actually the Int encoded deletion
> time.
> Here is an example in the code that does this check and will do the wrong
> thing if the deletion timestamp is even just a few seconds in the future:

> To prove that this is a problem, here is a stack trace of a machine trying to
> interpret the "localDeletionTime" value of a DeletedColumn as UTF-8 because
> the .isMarkedForDeletion() check failed:
