Subject Re: troubles with HBase unit tests using MiniMRCluster on 0.23.1-SNAPSHOT

Yes, but as Hitesh noted on MAPREDUCE-3654, it seems the Yarn client provider is not found
or used. (I don't know yet how all of this works...) So the issue with LocalClientProvider
not liking the MASTER_ADDRESS set to "test" by the mini Yarn cluster is merely a symptom.
Likewise perhaps the FNFE problem.

If you could spare a few minutes, that would be very helpful I think. Perhaps our POM needs
updating, some artifact is perhaps not being pulled in for testing, and while this was fine
for 0.23.0, that is no longer the case for 0.23.1+?


Best regards,
