He Yongqiang commented on HIVE-3585:
------------------------------------

So far i am still not convinced to have it as another builtin serde in Hive's 
core codebase. We initially did put some new serdes in contrib or 3rd party 
libs, examples include HBaseSerde and Zebra serde.

If you can make it work with existing Avro serde, it will also be great.
