> {code}
> root@b9ab37566005:/# hadoop daemonlog
> Usage: General options are:
> 	[-getlevel <host:port> <classname> [-protocol (http|https)]
> 	[-setlevel <host:port> <classname> <level> [-protocol (http|https)]
> Exception in thread "main" org.apache.hadoop.HadoopIllegalArgumentException: No arguments
specified
> 	at org.apache.hadoop.log.LogLevel$CLI.parseArguments(LogLevel.java:138)
> 	at org.apache.hadoop.log.LogLevel$CLI.run(LogLevel.java:106)
> 	at org.apache.hadoop.log.LogLevel.main(LogLevel.java:70)
> {code}
> I think we can catch the exception in the main method, and dump a log error message instead
of throw the stack which may frustrate users.
