> 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.
