-----------------------------------------------

    Description: 
Map only job (randomwriter, randomtextwriter) restarts from scratch [0% map 0% reduce] after RM restart.
It should resume from the last state when AM restarted.

        Summary: AM recovery does not work for map only jobs  (was: RM restart does not work for map only job)

It's got more to do with AM recovery itself. I observed this a while ago when browsing MR app code, but forgot to file the ticket.
