union

union

Unions of [T, null] transparently convert to nullable T, other types translate directly to Hive's unions of those types. However, unions were introduced in Hive 7 and are not currently able to be used in where/group-by statements. They are essentially look-at-only. Because the AvroSerde transparently converts [T,null], to nullable T, this limitation only applies to unions of multiple types or unions not of a single type and null.
