    Description

      since HIVE-16812 VectorizedOrcAcidRowBatchReader filters delete events based on min/max ROW__ID in the split which relies on hive.acid.index to be in the ORC footer.

      There is no way to generate hive.acid.index from a plain query as in HIVE-20699 and so we need to make sure that we generate a SARG into delete_delta/bucket_x based on stripe stats even the index is missing
