>                 Key: HIVE-6043
>                 URL: https://issues.apache.org/jira/browse/HIVE-6043
>             Project: Hive
>          Issue Type: Task

> We need to document incompatible changes. For example
> * HIVE-5372 changed object inspector hierarchy breaking most if not all custom serdes
> * HIVE-1511/HIVE-5263 serializes ObjectInspectors with Kryo so all custom serdes (fixed by HIVE-5380)
> * Hive 0.12 separates MapredWork into MapWork and ReduceWork which is used by Serdes
> * HIVE-5411 serializes expressions with Kryo which are used by custom serdes
