Vinod Kumar Vavilapalli commented on MAPREDUCE-2971:
----------------------------------------------------

Yes, this is because of MAPREDUCE-2908, I take the blame. I removed the method 
as FindBugs warned that method wasn't properly overridden because of a 
different argument - something of that sort. The removed method 
JobClient.displayJobList() and CLI.displayJobList() are essentially the same 
code.

The attached patch will bring that warning back. We should just change the 
visibility of CLI.displayJobList() to be public.
