[jira] Commented: (HIVE-298) Make branch 0.2 forward compatible with tables created with LazySimpleSerDe

["Joydeep Sen Sarma (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675819#action_12675819 ] 

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?

> 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.
