     [ https://issues.apache.org/jira/browse/HIVE-9936?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexander Pivovarov updated HIVE-9936:
--------------------------------------
    Description: 
In some cases DefaultUDAFEvaluatorResolver calls new AmbiguousMethodException(udafClass, null, null)  (line 94)
This will throw NPE because AmbiguousMethodException calls argTypeInfos.toString()
argTypeInfos is the second parameter and it can not be null.
