Subject [jira] Commented: (HIVE-655) Add support for user defined table generating functions
Date Thu, 19 Nov 2009 00:53:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779771#action_12779771
] 

Namit Jain commented on HIVE-655:
---------------------------------

Minor comments:

1. Remove author tag from AutoProgress
2. SemanticAnalyzer/TypeCheckProcFactory - when you are throwing SemanticException, add new
error messages in ErrorMsg
3. Do you want to enable auto progress by default  - this might break some existing script
operator applications.

> Provide a way for users to add a table generating function, i.e., functions that generate
multiple rows from a single input row. Currently, the only way to do it is via the TRANSFORM
clause which requires streaming the data.
