> HS2 leaks classloader due to `ReflectionUtils::CONSTRUCTOR_CACHE` with
> temporary functions + GenericUDF

> Key: HIVE-21971
> URL: https://issues.apache.org/jira/browse/HIVE-21971
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 2.3.4

> https://issues.apache.org/jira/browse/HIVE-10329 helped in moving away from
> hadoop's ReflectionUtils constructor cache issue
> (https://issues.apache.org/jira/browse/HADOOP-10513).
> However, there are corner cases where hadoop's {{ReflectionUtils}} is in use
> and this causes gradual build up of memory in HS2.
> I have observed this in Hive 2.3. But the codepath in master for this has not
> changed much.
> Easiest way to repro would be to add a temp function which extends
> {{GenericUDF}}. In {{FunctionRegistry::cloneGenericUDF,}} this would
> end up using {{org.apache.hadoop.util.ReflectionUtils.newInstance}} which in
> turn lands up in COSNTRUCTOR_CACHE of ReflectionUtils.
> {noformat}
> CREATE TEMPORARY FUNCTION dummy AS 'com.hive.test.DummyGenericUDF' USING JAR
> 'file:///home/test/udf/dummy.jar';
> select dummy();
