[jira] [Created] (HIVE-3833) object inspectors should be
initialized based on partition metadata
Namit Jain created HIVE-3833:
--------------------------------
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
