If you "scrub" this SSTable (either with the online or offline version of
"scrub") it will remove the corrupt data and re-write the rest of the
SSTable which isn't corrupt into a new SSTable. That is probably safer for
your data than deleting the entire set of data on this replica. When that's
done, restart the repair.
