[jira] [Created] (HIVE-5906) TestGenericUDFPower should use delta to compare doubles

Szehon Ho created HIVE-5906:
-------------------------------

             Summary: TestGenericUDFPower should use delta to compare doubles
                 Key: HIVE-5906
                 URL: https://issues.apache.org/jira/browse/HIVE-5906
             Project: Hive
          Issue Type: Bug
          Components: Tests
            Reporter: Szehon Ho
            Assignee: Szehon Ho


TestGenericUDFPower.testDoulePowerDecimal() uses junit's Assert.assertEquals(double, double) to test double equality on result of power udf function.

Due to floating-number convention, this does not always work.  This API is deprecated in favor of Assert.assertEquals(message, double, double, delta).
