[jira] [Created] (ORC-519) Incorrect ORC v1 specification of Decimal encoding

Brent Kerby created ORC-519:
-------------------------------

             Summary: Incorrect ORC v1 specification of Decimal encoding
                 Key: ORC-519
                 URL: https://issues.apache.org/jira/browse/ORC-519
             Project: ORC
          Issue Type: Bug
          Components: documentation
            Reporter: Brent Kerby


According to the ORC v1 specification ([https://orc.apache.org/specification/ORCv1/]), the SECONDARY (scale) stream in a Decimal column is encoded using Unsigned Integer RLE v1. However, observing the implementation and behavior of the C++ library, it is evident that the Signed Integer RLE v1 is what is actually used.
