> After a Parquet table is refreshed with selected "interesting" columns, a query whose
WHERE clause contains a condition on a "non interesting" INT64 column fails during run-time
pruning (calling match()) with:
> {noformat}
> org.apache.drill.common.exceptions.UserException: SYSTEM ERROR: ClassCastException: java.lang.Long
cannot be cast to java.lang.Integer
> {noformat}
>  Near-term fix suggestion: Catch the match() exception error, and instead do not prune
(i.e. run-time pruning would be disabled in such cases).
