> Impala should log when values overflow.  We probably don't want to log each value, that could be very many values.
> This is most useful on the scanner path.  For example, we had one table where the schema was int (int32) when it should have been bigint (int64).  This resulted in a hard to diagnose duplicate unique id issue.  It would have been much better if we just logged something like "1 billion values overflowed for col x"
