Zoltan Haindrich commented on HIVE-18137:
-----------------------------------------
I've done a deep dive in the history but its pretty hard to uncover when this
have changed...there are many renames...multiple different versions of the same
test (vec/nonvec;part/table;orc/text,x/y) - this is kinda like a matrix test...
> Schema evolution: newly inserted column value in pre-existing partition is
> masked to null
