Bowen Li updated FLINK-13755:
-----------------------------
Description:
Unlike UDFs that are persisted in Hive Metastore, Hive builtin functions are
registered into in-memory function catalog at runtime.
# We need to define the resolution order
# Alternatively, we can try to match Hive built-in functions in Flink and
eliminate the need of supporting them. The gap needs to be discovered first.
