Description

When the union type was introduced, full support for it wasn't provided. For instance, when working with a union that gets passed to LazyBinarySerde:

Caused by: java.lang.RuntimeException: Unrecognized type: UNION
	at org.apache.hadoop.hive.serde2.lazybinary.LazyBinarySerDe.serialize(LazyBinarySerDe.java:468)
	at org.apache.hadoop.hive.serde2.lazybinary.LazyBinarySerDe.serializeStruct(LazyBinarySerDe.java:230)
	at org.apache.hadoop.hive.serde2.lazybinary.LazyBinarySerDe.serialize(LazyBinarySerDe.java:184)
