Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.0.0
Reporter: Stevo Mitric
Add handling of map normalization upon creation in ArrayBasedMapBuilder.
Currently a map with keys 0.0 and -0.0 will behave as if they are separate
values. This will cause issues when doing GROUP BY on map types.
