             Summary: Incorrect statistical aggregate results when the inputs have constants infinity 
                 Key: SPARK-27768
                 URL: https://issues.apache.org/jira/browse/SPARK-27768
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Xiao Li


When the inputs contain the constant 'infinity', Spark SQL does not generate the expected results.
{code:java}
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('1'), (CAST('infinity' AS DOUBLE))) v(x);
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('infinity'), ('1')) v(x);
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('infinity'), ('infinity')) v(x);
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('-infinity'), ('infinity')) v(x);{code}
