Subject [jira] [Commented] (HIVE-2390) Add UNIONTYPE serialization support to LazyBinarySerDe

Suma Shivaprasad commented on HIVE-2390:
----------------------------------------

Carl,

I am working on a related feature to support UNIONTYPE in ThriftDeserializer as well.
Since I am a fairly new contributor to Hive and not aware of the existing issues in UNIONTYPE
feature, if someone could identify the missing pieces and raise jiras, i can take a stab at
it.

> 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: 
> {noformat}Caused by: java.lang.RuntimeException: Unrecognized type: UNION
