HADOOP-11827 patch from few days ago. I've noticed a minor bug in maybePrintStats logic which is called only when new directory is processed, and prints every 100K objects (effectively, there is a very low probability it'll ever print stats). The reason for this bug is that I was previously printing stats for every new directory, and later decided it's nicer to print stats for large number of new "objects" (files or directories) instead.
This is a minor issue - and since I'm refactoring this I've also changed the minor retry logic to make code nicer and more readable.
