> Working in the NN a lot for HA (HDFS-1623) I've come across a number of situations where
the tangled dependencies between NN components has been problematic for adding new features
and for testability. It would be good to untangle some of these and clarify what the distinction
is between the different components: NameNode, FSNamesystem, FSDirectory, FSImage, NNStorage,
and FSEditLog
