--------------------------------------------------------------------
I'm seeing this while running repair -pr. Three-cluster node, RF 3. Straight
upgrade from 1.0.12 to 1.1.8; no topology changes. I see two invalid shard
IDs, counts differ by more than one - sometimes even by 3000 or more. Seems
random to my eyes.
Our counters are in a composite column family, no TTLs in use. We *mostly*
increment by one, but sometimes more.
I did disablegossip, disablethrift, drain, upgrade, restart on every node in a
rolling fashion. Then I did upgradesstables and repair -pr on every node when
the entire cluster had been upgraded.
