Damien Carol updated HIVE-9767:
-------------------------------
Description:
There are issues in UDF never get exposed because the execution path is never
tested:
# Assume the ObjectInspector to be WritableObjectInspector not the
ObjectInspector pass to UDF
# Assume the input parameter to be Writable not respecting the ObjectInspector
pass to UDF
# Assume ConstantObjectInspector to be WritableConstantXXXObjectInspector
# The InputObjectInspector does not match OutputObjectInspector of previous
stage in UDAF
# The execution path involving convertIfNecessary is never been tested
Attach a patch to fix those.
