PS26, Line 1157:
Could you comment on why this test was removed ?  It was introduced in 
IMPALA-13405 and I thought it was useful for the memory estimate of Aggs  in a 
nested view (based on the cardinality estimate). I suppose this scenario is 
covered elsewhere ?

Any idea why the cost of this operator did not change even though the 
cardinality went up by 3 orders of magnitude.  This may not be related to this 
patch.
