David Mollitor created ORC-834:
----------------------------------

             Summary: Do Not Convert to String in DecimalFromTimestampTreeReader
                 Key: ORC-834
                 URL: https://issues.apache.org/jira/browse/ORC-834
             Project: ORC
          Issue Type: Improvement
          Components: Java
            Reporter: David Mollitor
            Assignee: David Mollitor


Seen this elsewhere and it doesn't usually end well.  Do not convert-to-string and then parse-from-string.  Go directly to Decimal from the values provided.
