These tests functionally test whether the following type of files are able to be scanned properly: 1) Add a parquet file with multiple blocks such that each node has to scan multiple blocks. 2) Add a parquet file with multiple blocks but only one row group that spans the entire file. Only one scan range should do any work in this case.
