   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   We cannot fix the shuffle mechanism until we have partition stats, or ShuffleReaderExec will attempt to read empty partitions, causing an error.
   
   **Describe the solution you'd like**
   Scheduler should receive partition stats and only try and read from non-empty shuffle partitions.
   
   **Describe alternatives you've considered**
   As a workaround we could write empty shuffle files for empty partitions.
   
   **Additional context**
   None
