> Add column lineage information to the pre execution hooks
> ---------------------------------------------------------
>
> Key: HIVE-1131
> URL: https://issues.apache.org/jira/browse/HIVE-1131
> Project: Hadoop Hive
> Issue Type: New Feature
> Components: Query Processor
> Reporter: Ashish Thusoo
> Assignee: Ashish Thusoo
> Attachments: HIVE-1131.patch, HIVE-1131_2.patch, HIVE-1131_3.patch,
> HIVE-1131_4.patch, HIVE-1131_5.patch, HIVE-1131_6.patch, HIVE-1131_7.patch
>
>
> We need a mechanism to pass the lineage information of the various columns of
> a table to a pre execution hook so that applications can use that for:
> - auditing
> - dependency checking
> and many other applications.
> The proposal is to expose this through a bunch of classes to the pre
> execution hook interface to the clients and put in the necessary
> transformation logic in the optimizer to generate this information.
