Steve Loughran commented on YARN-8338:
--------------------------------------

BTW, maven shading on the hadoop minicluster is now complaining about .class conflict between objenesis and a mockito JAR, at least on a run of HADOOP-15407. 
{code}

I've done a scan for any mockito refs other than in test & can't see them, so I'm not sure what is happening. Something, somehow, is pulling in a mockito onto the hadoop-minicluster. Except I can't see it. Anyway, not sure how much it actually matters....
