--------------------------------

             Summary: object inspectors should be initialized based on partition metadata
                 Key: HIVE-3833
                 URL: https://issues.apache.org/jira/browse/HIVE-3833
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Namit Jain
            Assignee: Namit Jain


Currently, different partitions can be picked up for the same input split based on the
serdes' etc. And, we dont allow to change the schema for LazyColumnarBinarySerDe.
Instead of that, different partitions should be part of the same split, only if the
partition schemas exactly match. The operator tree object inspectors should be based
on the partition schema. That would give greater flexibility and also help using binary serde
with rcfile
