> Parquet 1.7.0 renames package name to "org.apache.parquet", need to adjust {{ParquetRelation.enableLogForwarding}} accordingly to avoid noisy log output.
> A better approach than simply muting these log lines is to redirect Parquet logs via SLF4J, so that we can handle them consistently. In general these logs are very useful. Esp. when used to diagnosing Parquet memory issue and filter push-down.
