      Description

      In distcp, -delete and -diff options are mutually exclusive. HDFS-8828 brought strictly checking which makes the existing applications (or scripts) that work just fine with both -delete and -diff options previously stop performing because of the java.lang.IllegalArgumentException: Diff is valid only with update options exception.

      To make it backward incompatible, we can ignore the -delete option, given -diff option, instead of exiting the program. Along with that, we can print a warning message saying that Diff is valid only with update options, and -delete option is ignored.
