Hyukjin Kwon updated SPARK-23122:
---------------------------------
Environment: (was: Seems we allow many other ways to register UDFs in
SQL statements. Some are in {{SQLContext}} and some are in \{{Catalog}}.
These are also inconsistent with Java / Scala APIs. Seems we better deprecating
them and put the logics into \{{UDFRegistration}} (\{{spark.udf.register*}}).
Please see this discussion too -
