>
> CompactionManager.getBuckets is nondeterministic as explained in the parent
> issue.
> This can be fixed either by sorting in getBuckets, or requiring that the
> iterable passed be sorted already. Either is fine.
> We also need to add some unit tests to CompactionManagerTest for getBuckets.
> We need to decouple getBuckets a little to do this sanely; rather than
> examining sstable length directly or introducing some extra interface, let's
> declare getBuckets as
> static Set<List<T>> getBuckets(Iterable<Pair<T, Integer>> files, long min)
> where the integer in the pair is the file size. Then you can write tests
> against Strings instead of SSTableReaders.
