Vinod Kumar Vavilapalli resolved MAPREDUCE-5215.
------------------------------------------------
Resolution: Won't Fix
bq. I agree, the method was marked as package private, so we made no guarantees
about its availability. We don't want to set a precedent for this.
Seems like there is enough agreement. There are far too many things like this
if we go down this path.
Closing this for now, let's revisit again in future if need be.
> mapreduce.Job is missing getJobClient() so its incompatible with MR1

> The method {{org.apache.hadoop.mapred.JobClient getJobClient()}} is in MR1's
> {{mapreduce.Job}} but doesn't exist in MR2's, which makes them incompatible.
> MR2's implementation of {{Job}} doesn't use a JobClient object, but we can
> create one and return it.
