> While running the dtest {{upgrade_through_versions_test.py:TestRandomPartitionerUpgrade.upgrade_test}},
the test is failing due to a large number of exceptions in the logs related to compaction.
Here is a snippet of one. The full log is attached. These exceptions occurred after upgrading
to trunk. The cluster had already upgraded 1.2 -> 2.0 -> 2.1 successfully.
