      Description

      MAPREDUCE-5974 added in ability to instantiate multiple OCs, but if none of them are able to load it "throws" only a final a generic message: "Unable to initialize any output collector"

      The older behaviour was to throw the actual instantiation exception back, so it makes it to client logs with an actual meaningful error.

      Now the clients need to go take a look at the task's logs to find the WARNs that represent the failure in instantiation.
