> Now we have {{SparkMapJoinResolver}} in place. But at the moment, it doesn't
> handle the map join task created by upstream SkewJoinResolver, i.e. those
> wrapped in a ConditionalTask. We have to implement this part for runtime skew
> join to work on spark. To do so, we can borrow logic from {{MapJoinResolver}}.
