Brandon Williams commented on CASSANDRA-3156:
---------------------------------------------
Also some spurious digest mismatches mixed in, even though I have no reason to
suspect there is actually a mismatch in my dev env (3 nodes, rf=2):
DEBUG 03:15:59,823 Digest mismatch:
org.apache.cassandra.service.DigestMismatchException: Mismatch for key
DecoratedKey(20580074455139572311737153648595094740, 30363933)
