Ashutosh Chauhan updated PIG-2951:
----------------------------------

    Attachment: pig-2951.patch

Here is the patch which does runtime checking for overflows/underflows and throws exception in case it detects overflows/underflows.
I followed CMU's CERT Oracle Secure Coding Standard for Java https://www.securecoding.cert.org/confluence/display/java/NUM00-J.+Detect+or+prevent+integer+overflow for this. Hopefully, extra CPU cycles it will incur aren't too many.

> With very large (or very small) integer values there is a possibility of overflow (or underflow) errors. Worse thing is instead of failing, this currently results in incorrect results being returned, thereby leaving user with no clue that some of the tuples may have wrong value.
