Subject [jira] [Commented] (CASSANDRA-3156) assertion error in RowRepairResolver
Date Thu, 08 Sep 2011 03:23:08 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13099732#comment-13099732
] 

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,
