[jira] [Created] (HIVE-13251) Decimal in AVRO file generated from previous hive can't be read

Aihua Xu created HIVE-13251:
-------------------------------

             Summary: Decimal in AVRO file generated from previous hive can't be read 
                 Key: HIVE-13251
                 URL: https://issues.apache.org/jira/browse/HIVE-13251
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.1.0
            Reporter: Aihua Xu
            Assignee: Aihua Xu


HIVE-7174 makes the avro schema change to match avro definition, while it breaks the compatibility if the file is generated from the previous Hive. We should allow to read old file format "precision" : "4", "scale": "8", but write in the new format.
