Yin Huai commented on SPARK-6023:
---------------------------------
The problem is when we do plan.transformUp to replace the relation, we will
never visit the destination relation in an InsertIntoTable command.
> ParquetConversions fails to replace the destination MetastoreRelation to
> ParquetRelation2
> -----------------------------------------------------------------------------------------
