[jira] [Created] (HIVE-27145) Use StrictMath for remaining Math functions as followup of HIVE-23133

Himanshu Mishra created HIVE-27145:
--------------------------------------

             Summary: Use StrictMath for remaining Math functions as followup of HIVE-23133
                 Key: HIVE-27145
                 URL: https://issues.apache.org/jira/browse/HIVE-27145
             Project: Hive
          Issue Type: Task
          Components: UDF
            Reporter: Himanshu Mishra
            Assignee: Himanshu Mishra


[HIVE-23133|https://issues.apache.org/jira/browse/HIVE-23133] started using {{StrictMath}} for {{cos, exp, log}} UDFs to fix QTests failing as results vary based on hardware when using Math library.

Follow it up by using {{StrictMath}} for other Math functions that can have same impact of underlying hardware namely, {{sin, tan, asin, acos, atan, sqrt, pow, cbrt}}.

[JDK-4477961](https://bugs.openjdk.org/browse/JDK-4477961) (in Java 9) changed radians and degrees calculation leading to Q Test failures when tests are run on Java 9+, fix such tests.
