> 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.
