Namit Jain commented on HIVE-3833:
----------------------------------
Refreshed, all the tests passed.
https://issues.apache.org/jira/secure/attachment/12564718/hive.3833.14.patch contains all the changes.
The phabricatr entry does not contain the changes for test results compiler files, since it was exceeding the limit.

> 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
