Xuefu Zhang commented on HIVE-8793:
-----------------------------------
+1.
Patch looks good. We don't need a couple of followup JIRAs:
1. Better printing of the work graph. We should print in topological order
always.
2. Additional work is needed to make map join work with this change.
> Refactor to make splitting SparkWork a physical resolver [Spark Branch]

> Currently, HIVE-8622 is implemented based on an assumption, that for a map
> join query, a BaseWork would not have multiple children. By testing through
> subquery_multiinsert.q did reveal that's the case. But, we need to
> investigate on this, and make sure this won't happen in general.
