    • HIVE-298. Add LazySimpleSerDe. (zshao)

    Description

      We can easily make branch 0.2 forward-compatible with tables created with LazySimpleSerDe (starting branch 0.3), since LazySimpleSerDe has exactly the same serialized format as TCTLSeparatedProtocol and MetadataTypedColumnsetSerDe.

      The plan is to directly map it to TCTLSeparatedProtocal.
