Hi guys, We're running a three node cluster of cassandra 1.1 servers, originally 1.0.7 and immediately after the upgrade the error logs of all three servers began filling up with the following message:
ERROR [ReplicateOnWriteStage:177] 2012-05-31 08:17:02,236 CounterContext.java (line 381) invalid counter shard detected; (3438afc0-7e71-11e1-0000-da5a9d01e7f7, 3, 4) and (3438afc0-7e71-11e1-0000-da5a9d01e7f7, 3, 7) differ only in count; will pick highest to self-heal; this indicates a bug or corruption generated a bad counter shard ERROR [ValidationExecutor:20] 2012-05-31 08:17:01,570 CounterContext.java (line 381) invalid counter shard detected; (343cf580-7e71-11e1-0000-ebc411012bff, 14, 27) and (343cf580-7e71-11e1-0000-ebc411012bff, 14, 21) differ only in count; will pick highest to self-heal; this indicates a bug or corruption generated a bad counter shard The counts change but the errors are constant. What is the best course of action? Google only turns up the source code for these errors. Thanks! Charles
