Chris Herron commented on CASSANDRA-4417:
-----------------------------------------
bq. Probably, how was it deleted/recreated. Did you drop and recreate?
Yes, dropped (the schema migration flavor) and recreated a CF of the same name.
bq. Perform the same test without the upgradesstables part (i.e. only the
writes and reads). If so, does that change something?
Have already tested that scenario. Running this load test without the
concurrent upgradesstables compaction activity, the problem does not exhibit.
bq. during that test, is there anything involving streaming going on (a repair,
a node bootstrapping/moving/decommissioning)?
Not that I know of. I can test again and monitor for streaming activity to see.
By the way, as we've been testing in preparation for a 1.1.x upgrade, we were
seeing symptoms of CASSANDRA-4571, CASSANDRA-4687 as well as this issue on C*
1.1.6. In investigating CASSANDRA-4687 we disabled key cache, repeated the
load+upgradesstables test and these invalid counter shard warnings did not
appear.
