Boaz Ben-Zvi updated DRILL-7244:
--------------------------------
Description:
See -DRILL-7+240+-, 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.
