Ted Yu updated FLINK-7897:
--------------------------
    Description: 
nio.Files#delete() provides better clue as to why the deletion may fail:

https://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#delete(java.nio.file.Path)

Depending on the potential exception (FileNotFound), the call to 
localFile.exists() may be skipped.
