> In `CompactionTask#buildCompactionCandidatesForAvailableDiskSpace` with LCS, 
> if node has limited disk space and can't remove any sstable from L0 or L1 in 
> `LeveledCompactionTask#reduceScopeForLimitedSpace`, 
> `LeveledCompactionTask#partialCompactionsAcceptable` will throw 
> `UnsupportedOperationException`.
> We should handle `LeveledCompactionTask#partialCompactionsAcceptable` more 
> gracefully with `return level <= 1` or simply `true` since 
> `reduceScopeForLimitedSpace` only removes sstable from L0 or L1.
