Cool. I asked to check if this was a planned divergence & not a merge

Due to late binding, classpath ordering and identical classnames, there¹s
a sensation of sleepwalking into a minefield.

The qtests do not test any of these cluster classpath issues due to the
in-thread mixed nature of the minicluster (like in HIVE-9350).

We¹ll get errors only when MRv2/MRv1 hits a non-existent method in

Jdiff shows removed constructors, but hopefully nobody uses those.
