> SJ removal backfired a bit when I was testing stuff - because of the additional opportunities paralleledges may enable ; because it will increased the shuffled memory amount and/or even make MJ broadcast inputs larger
> set hive.optimize.shared.work.semijoin=false by default for now
> right now it's better to leave dppunion to pick up these cases instead of removing the SJ fully - after HIVE-24376 we might enable it back
