Rui Li commented on HIVE-11133:
-------------------------------
[~stakiar], the plan in your last comment doesn't seem correct. Looking at the
"raw query plan", Stage-2 is the root stage which only contains Map 4. However,
in the explain output, the vertex dependency is for Stage-1, although it says
it's for root stage.
> Support hive.explain.user for Spark
