dhruba borthakur commented on HIVE-298:
---------------------------------------
I like this approach versus making branches forward-compatible. There is
still some inconsistency, because the change to the 0.20 branch is more like a
new feature rather than a bug fix.
> Make branch 0.2 forward compatible with tables created with LazySimpleSerDe

> Project: Hadoop Hive
> Issue Type: Improvement

>
> 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.
