Subject invalid counter shard detected
Date Wed, 31 Oct 2012 21:01:01 GMT
Hi guys!

We are getting the following message in our logs

ERROR [CompactionExecutor:535] 2012-10-31 12:14:14,254
(line 381) invalid counter shard detected;
(ea9feac0-ec3b-11e1-0000-fea7847157bf, 1, 60) and
(ea9feac0-ec3b-11e1-0000-fea7847157bf, 1, -60) differ only in count; will
pick highest to self-heal; this indicates a bug or corruption generated a
bad counter shard

Googling about it we found the issue CASSANDRA-4417 so we know this is an
open bug.

We have verified that the value of those counters is corrupted, we have two
nodes and if you request data with CL ONE you get different values
depending on what node used. But with CL ALL works ok.

There is a way to fix the corrupted counters?
