> Sub-task of HIVE-8406.
> 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}}.
