> We encountered an issue recently that one customer's structured streaming job failed to read delta file. 
> The temporary file exists but it was not successfully renamed to final delta file path. 
> We currently don't check if renamed file exists but assume it successful. As the result, failing to read delta file assumed to be committed in last batch makes re-triggering the job impossible. 
> We should be able to do a check against checkpoint renamed file to prevent such difficulty in advance.
