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. | ]]></ac:plain-text-body></ac:structured-macro> |
