[GitHub] [arrow-datafusion] Ted-Jiang opened a new issue #1462: fix calculate total_rows in many_to_many_hash_partition

Ted-Jiang opened a new issue #1462:
URL: https://github.com/apache/arrow-datafusion/issues/1462


   **Describe the bug**
   
   `        let total_rows: usize = output_partitions.iter().map(|x| x.len()).sum();
   `
   is sum the total RecordBatch number.
   
   For now empty RecordBatch will send to next plan so the total_RecordBatch equals total_rows
   **To Reproduce**
   https://github.com/apache/arrow-datafusion/pull/1459
   **Expected behavior**
   `let total_rows: usize = output_partitions
               .iter()
               .map(|x| x.into_iter().map(|x| x.num_rows()).sum::<usize>())
               .sum();`
   is sum the total row number
