> 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.
