> In HdfsServerConstants, it may be better to define StartupOption.name as final since
it will not and should not be modified after initialization. For example, in NameNode.java,
the printUsage function prints out multiple startup options' names. The modification/change
of the StartupOption.name may cause invalid usage message. Although right now there is no
methods to change/set the value of StartupOption.name, it is better to add the final keyword
to make sure.
