Cathy Daw updated CASSANDRA-2918:
---------------------------------
Comment: was deleted
(was: This looks more to me like a WRITE with CL.Q bug as the source of the
problem. But shouldn't have repair detected that node1 and node2 were out of
sync?
* 3 node cluster / KS with RF=3 / 2 nodes up
* Insert 1000 rows on node1 with CL=QUORUM
** node1:691 rows
** node2:1000 rows
** node3: down
* Repair node3
** node1:691 rows
** node2:1000 rows
** node3: 691 rows
)
> After repair, one row missing from query when two rows expected
