[jira] [Created] (HIVE-22883) PPD is misconfigured in VectorizedOrcAcidRowBatchReader

Zoltán Borók-Nagy created HIVE-22883:
----------------------------------------

             Summary: PPD is misconfigured in VectorizedOrcAcidRowBatchReader
                 Key: HIVE-22883
                 URL: https://issues.apache.org/jira/browse/HIVE-22883
             Project: Hive
          Issue Type: Bug
            Reporter: Zoltán Borók-Nagy


In VectorizedOrcAcidRowBatchReader.findMinMaxKeys() loop-local variable 'colStats' doesn't depend on the loop variable 'i', but on 'firstStripeIndex'.

[https://github.com/apache/hive/blob/59d8665cba4fe126df026f334d35e5b9885fc42c/ql/src/java/org/apache/hadoop/hive/ql/io/orc/VectorizedOrcAcidRowBatchReader.java#L594]

Because of that the values used for PPD will be invalid.
