> Its the opposite problem of what we thought in HIVE-8701.
> SparkMapJoinOptimizer does combine nested mapjoins into one work due to removal of RS
for big-table.  So we need to enhance the check to calculate if all the MapJoins in that work
(spark-stage) will fit into the memory, otherwise it might overwhelm memory for that particular
spark executor.
