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

             Summary: Remove localTimestamp from merkle-tree calculation (for 
tombstones)
                 Key: CASSANDRA-5398
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5398
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Christian Spriegel
            Priority: Trivial
         Attachments: V1.patch

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.
