waterlx commented on issue #492: Should issue an error message when no data file to delete
URL: https://github.com/apache/incubator-iceberg/issues/492#issuecomment-534425688
 
 
   I used the following API, trying to delete a data file
   ```
   table.newDelete().deleteFile("file:///path1")
   ```
   And got the following message: INFO SnapshotProducer: `Committed snapshot xxxxx (StreamingDelete)`
   I thought the deletion succeeded, but actually it did not, because the data file is "file:/path1", not "file:///path1".
   While [file URI scheme](https://en.wikipedia.org/wiki/File_URI_scheme) is another topic, but it would be better to issue an error/warning here when files to delete are not in data files.
