--------------------------------------

             Summary: Handle schema evolution from float, double and decimal
                 Key: HIVE-20437
                 URL: https://issues.apache.org/jira/browse/HIVE-20437
             Project: Hive
          Issue Type: Bug
            Reporter: Janaki Lahorani
            Assignee: Janaki Lahorani


When data created as float, double or decimal in parquet format is read back using some other type, errors are seen.  Parquet should behave just like any other format.  If the value is valid for the new type, data is retuned otherwise null has to be returned.
