> One problem I observed at HA branch is that namenode -format doesn't pick up 
> the right configured dfs.namenode.name.dir.NameServiceId. In this case, 
> ``namenode -format'' will format the default directory instead of the 
> configured one, while namenode will use the correct one. 
> The root cause is that NameNode.initializeGenericKeys() is only invoked at 
> the NameNode constructor. So it doesn't get called by static methods like 
> format and finalize.
