> The fix for IMPALA-7668 introduced a bug wherein a UDF calling other functions within the same jar would fail with errors like:
> {code}
> WARNINGS: UDF WARNING: Hive UDF path=hdfs://localhost:20500/test-warehouse/impala-hive-udfs2.jar class=org.apache.impala.ImportsNearbyClassesUdf failed due to: ImpalaRuntimeException: UDF::evaluate() ran into a problem.
> CAUSED BY: ImpalaRuntimeException: UDF failed to evaluate
> CAUSED BY: InvocationTargetException: null
> CAUSED BY: NoClassDefFoundError: org/apache/impala/UtilForUdf
> CAUSED BY: ClassNotFoundException: org.apache.impala.UtilForUdf
> {code}
> I believe this is caused by over-eagerly closing the associated class loader, which was introduced recently in IMPALA-7668.
