Subject [jira] [Commented] (HIVE-10708) Add SchemaCompatibility check to AvroDeserializer
Date Wed, 09 Sep 2015 04:32:45 GMT


Swarnim Kulkarni commented on HIVE-10708:

Decided to add a simple flag to turn this compatibility check on. Keeping this flag off by
default for backwards compatibility.

> 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
