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.
