Harish Butani commented on HIVE-13112:
--------------------------------------
The HookContext gets the Lineage from the SessionState. And AFAICT the Lineage
in SessionState is only being set in the MoveTask.
> Expose Lineage information in case of CTAS

> This is not happening because Lineage is being exposed by MoveTask which
> checks for a LoadTableDesc. In case of CTAS the table is created after the
> MoveTask.
> Proposed solution is to add a flag to CreateTableDesc to track a CTAS
> operation, and have the DDLTask expose the lineage if this flag is set.
