----------------------------------

             Summary: [SQL] bug in CaseWhen resolve
                 Key: SPARK-3362
                 URL: https://issues.apache.org/jira/browse/SPARK-3362
             Project: Spark
          Issue Type: Bug
            Reporter: Adrian Wang


select case x when 0 then null else y/x end from t;
will lead to an match error in toHiveString() when output, because spark would consider the output is always NullType, which is not right.
