Egor Pahomov commented on SPARK-16228:
--------------------------------------
[~srowen] "blocker" is questionable, I agree. I just believe, that everything
which prevent you from moving from 1.6.1 to 2.0 without major code changes is
"blocker". It's just if I move and such bug would be there a lot of my analysts
notebook would be invalid.
> "Percentile" needs explicit cast to double
