Joydeep Sen Sarma commented on HIVE-298:
----------------------------------------
This doesn't make sense .. (can't keep putting forward compatibility changes in
older branches).
Perhaps we need to have some layer of indirection (I think for a while hive1 -
we had aliases for serdes) - so that we can default to different
implementations (for delimited text deserialization) in different versions
without breaking compatibility. thoughts?
> Make branch 0.2 forward compatible with tables created with LazySimpleSerDe

> Project: Hadoop Hive
> Issue Type: Improvement
> Reporter: Zheng Shao
>
> 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.
