beliefer opened a new pull request #33822: URL: https://github.com/apache/spark/pull/33822
### What changes were proposed in this pull request? Spark SQL includes a data source that can read data from other databases using JDBC. Spark also supports the case-insensitive option `pushDownPredicate`. According to http://spark.apache.org/docs/latest/sql-data-sources-jdbc.html, If set `pushDownPredicate` to false, no filter will be pushed down to the JDBC data source and thus all filters will be handled by Spark. But I find it still be pushed down to JDBC data source. ### Why are the changes needed? Fix bug `pushDownPredicate`=false failed to prevent push down filters to JDBC data source. ### Does this PR introduce _any_ user-facing change? 'No'. The output of query will not change. ### How was this patch tested? Jenkins test. -- This is an automated message from the Apache Git Service.
