> Hive stores the stripe stats in the ORC files. During select, these stats are used to create the SARG. The SARG is used to reduce the records read from the delete-delta files. Currently, in case where the number of stripes are more than 1, the SARG generated is not proper as it uses the first stripe index for both min and max key interval. The max key interval should be obtained from last stripe index.
