NameNode format doesn't pick up dfs.namenode.name.dir.NameServiceId configure
-----------------------------------------------------------------------------

                 Key: HDFS-3013
                 URL: https://issues.apache.org/jira/browse/HDFS-3013
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: ha, name-node
    Affects Versions: 0.23.0, HA branch (HDFS-1623)
            Reporter: Mingjie Lai


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.
