Review Comment:
Yes, just I think it would be better to make the exception message something
like "Error getting a slot value".
If an exception happens here, why do we log it on info level and return 0?
In Comparator zero means equality.
Maybe it's better to log it on error level and throw a Hive-specific runtime
exception?
