Key: HIVE-9767
URL: https://issues.apache.org/jira/browse/HIVE-9767
Project: Hive
Issue Type: Bug
Components: UDF
Reporter: Daniel Dai

There are issues in UDF never get exposed because the execution path is never
tested:
1. Assume the ObjectInspector to be WritableObjectInspector not the
ObjectInspector pass to UDF
2. Assume the input parameter to be Writable not respecting the ObjectInspector
pass to UDF
3. Assume ConstantObjectInspector to be WritableConstantXXXObjectInspector
4. The execution path involving convertIfNecessary is never been tested
Attach a patch to fix those.
