> The cassandra dtest for upgrading with RandomPartitioner is showing a potential issue with counters during a mixed-version upgrade.
> The test starts with a 3 node cluster on 1.1 (RF=2).
> In turn, the following is performed on each node:
>   * node gets 25k counter updates distributed across 100 counter cells. (CL=all)
>   * node is drained and shutdown
>   * node is updated to 1.2, started up, and upgradesstables is run
>   * counter values are checked again (CL=one)
> The steps above succeed for the first node, but fail on the second node. The failure isn't because the counters are wrong -- they don't seem to be present at all.
> I tried adding an additional flush before the drain, and this actually seems to have increased the number of counters not found.
> To run the test with dtest/nose:
> set PRINT_DEBUG=true
> then run nosetests -vs upgrade_through_versions_test:TestRandomPartitionerUpgrade.upgrade_test_mixed
