[jira] [Created] (HIVE-10708) Add SchemaCompatibility check to AvroDeserializer

Swarnim Kulkarni created HIVE-10708:
---------------------------------------

             Summary: Add SchemaCompatibility check to AvroDeserializer
                 Key: HIVE-10708
                 URL: https://issues.apache.org/jira/browse/HIVE-10708
             Project: Hive
          Issue Type: Improvement
          Components: Serializers/Deserializers
            Reporter: Swarnim Kulkarni
            Assignee: Swarnim Kulkarni


Avro provides a nice API[1] to check if the given reader schema can be used to deserialize the data given its writer schema. I think it would be super nice to integrate this into the AvroDeserializer so that we can fail fast and gracefully if there is a bad schema compatibility
