-----------------------------------------
Summary: fix potential NPE in DefaultUDAFEvaluatorResolver
Key: HIVE-9936
URL: https://issues.apache.org/jira/browse/HIVE-9936
Project: Hive
Issue Type: Bug
Components: UDF
Reporter: Alexander Pivovarov
Assignee: Alexander Pivovarov
In some cases DefaultUDAFEvaluatorResolver calls new
AmbiguousMethodException(udafClass, null, null)
This will throw NPE because AmbiguousMethodException calls
argTypeInfos.toString()
argTypeInfos is the second parameter and it can not be null.
