> 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
