Aihua Xu commented on HIVE-13251:
---------------------------------
OK. Seems we are trying to read based on file schema and then convert based on
record schema since record schema may not match the file.
> hive can't read the decimal in AVRO file generated from previous version

> 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.
