Looking at the source code for AbstractGenericUDAFResolver, the following
(non-deprecated) method should be called:
public GenericUDAFEvaluator getEvaluator(GenericUDAFParameterInfo info)
It is called by hiveUdfs.scala (master branch):
val parameterInfo = new
SimpleGenericUDAFParameterInfo(inspectors.toArray, false, false)
resolver.getEvaluator(parameterInfo)
