It does have backward compat > Document incompatible changes in Hive 0.12 and trunk > ---------------------------------------------------- > > Key: HIVE-6043 > URL: https://issues.apache.org/jira/browse/HIVE-6043 > Project: Hive > Issue Type: Task > Reporter: Brock Noland > Priority: Blocker > > 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 > * HIVE-4827 removed the flag of "hive.optimize.mapjoin.mapreduce" (This flag was introduced in Hive 0.11 by HIVE-3952). -- This message was sent by Atlassian JIRA (v6.1.4#6159)
