      Description

      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
