[jira] [Created] (DRILL-7244) Run-time rowgroup pruning match()
fails on casting a Long to an Integer
Boaz Ben-Zvi created DRILL-7244:
-----------------------------------
Summary: 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: Bug
Components: Storage - Parquet
Affects Versions: 1.17.0
Reporter: Boaz Ben-Zvi
Assignee: Boaz Ben-Zvi
Fix For: 1.17.0
See DRILL-7062, 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.
