Vova Vysotskyi resolved DRILL-7244.
-----------------------------------
Resolution: Fixed
Fixed in the scope of DRILL-7273 - checked whether the schema for row group is
changed and rebuilt filter expression with updated types to add new casts.
> Run-time rowgroup pruning match() fails on casting a Long to an Integer
> -----------------------------------------------------------------------
>
> Key: DRILL-7244
> URL: https://issues.apache.org/jira/browse/DRILL-7244
> Project: Apache Drill
> Issue Type: Sub-task
> Components: Storage - Parquet
> Affects Versions: 1.17.0
> Reporter: Boaz Ben-Zvi
> Assignee: Vova Vysotskyi
> Priority: Major
> Fix For: 1.17.0
>
>
> See DRILL-7240 , where a temporary workaround was created, skipping pruning
> (and logging) instead of this failure:
> 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}
> A long term solution is to pass the whole (or the relevant part of the)
> schema to the runtime, instead of just passing the "interesting" columns.
