      Description

      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 (HIVE-4825) separates MapredWork into MapWork and ReduceWork which is used by Serdes
      • HIVE-5411 serializes expressions with Kryo which are used by custom serdes
      • HIVE-4827 removed the flag of "hive.optimize.mapjoin.mapreduce" (This flag was introduced in Hive 0.11 by HIVE-3952).
