> *Scenario:*
> Current behaviour for the dfsrouteradmin command is: First argument should be valid one. What ever value we give as the second argument, the command is successfull.
>  
> *Examples:*
> hdfs dfsrouteradmin -safemode enter leave
> hdfs dfsrouteradmin -safemode leave enter
> hdfs dfsrouteradmin -safemode get jashfuesfhsk
> hdfs dfsrouteradmin -safemode leave leave
>  
> With the above examples, command is successfull for the first argument.
>  
> *Expected:*
> Add check to have single valid argument to the safemode command
>
