> The VectorExtractRow class does not preserve the order of the key/value pairs when going
from MapColumnVector to a Map object.  This causes Q file differences in tests with the MAP
data type making it seem like we are getting Wrong Results (well, actually we are).
> When LazyMap class (for example) adds key/value pairs to its "map" it uses a LinkedHashSet
to preserve insert order.
> FYI: [~teddy.choi]
