Review Comment:
   This bit seems repetitive in Spark and Flink. What about adding a new method 
to `Util`?
   
   ```
   public static boolean mayHaveBlockLocations(FileIO io, String location) {
     if (usesHadoopFileIO(io, location)) {
       ...
       return LOCALITY_WHITELIST_FS.contains(scheme);
     }
   
     return false;
   }
   ```
   
   I feel it would align well with other methods in `Util` like 
`blockLocations`.
