>
> Key: DRILL-7240
> URL: https://issues.apache.org/jira/browse/DRILL-7240
> Project: Apache Drill
> Issue Type: Sub-task
> Components: Storage - Parquet
> Affects Versions: 1.17.0
> Reporter: Boaz Ben-Zvi
> Assignee: Boaz Ben-Zvi
> Priority: Major
> Labels: ready-to-commit
> Fix For: 1.17.0
>
>
> 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).
