Christian Spriegel commented on CASSANDRA-5398:
-----------------------------------------------
[~jbellis]: Would this ticket be a candidate for 1.2? It seems repair is
getting a lot of attention lately, so there might be interest in reducing
overrepair whereever possible.
> Remove localTimestamp from merkle-tree calculation (for tombstones)

> DeletedColumn and RangeTombstone use the local-timestamp to update the digest
> during repair.
> Even though its only a second-precision timestamp, I think it still causes
> some differences in the merkle tree, therefore causing overrepair.
> I attached a patch on trunk that adds a modified updateDigest() to
> DeletedColumn, which does not use the value field for its calculation.
