SPARK-51029 (GitHub PR [1]) removes `hive-llap-common` from Spark binary
distribution, which technically
breaks the feature "Spark SQL supports integration of Hive UDFs, UDAFs and
UDTFs"[2], more precisely, it change
Hive UDF support from batteries included to not.
In details, when user runs a query like CREATE TEMPORARY FUNCTION hello AS
'my.HelloUDF', it triggers
o.a.h.hive.ql.exec.FunctionRegistry initialization, which also initializes the
Hive built-in UDFs, UDAFs and
UDTFs[3], then NoClassDefFoundError ocuurs due to some built-in UDTFs depend on
class in hive-llap-common.

Currently (v4.0.0-rc2), user must add the hive-llap-common jar explicitly, e.g.
by using
--packages org.apache.hive:hive-llap-common:2.3.10, to fix the
NoClassDefFoundError issue, even the my.HelloUDF
does not depend on any class in hive-llap-common, this is quite confusing.
