---------------------------------------------
+1, will commit with a small change (we need to filter suspect sstables) once
CI completes:

> [DateTieredCompactionStrategy.getMaximalTask|https://github.com/apache/cassandra/blob/cassandra-3.0/src/java/org/apache/cassandra/db/compaction/DateTieredCompactionStrategy.java#L393-393]
> creates a compaction task for all of a tables sstables, instead of just the
> repaired/unrepaired subset it's responsible for.
> This compacts repaired and unrepaired sstables together, effectively demoting
> repaired data to unrepaired. Also, since both the repaired and unrepaired
> strategy instances are trying to compact the same sstables, there's a 1
> minute delay waiting for {{CompactionManager.waitForCessation}} to time out
> before anything happens.
> Here's the script I used to duplicate:
