> Rest server doesn't start successfully, but it was bad that I can't find any
> error message indicating that server fails to start and why failure happens.

> at org.apache.hadoop.hbase.rest.RESTServer.main(RESTServer.java:424)
> {code}
> But these exceptions are caught without any messages printed.
> {code:java}
> org.apache.hadoop.hbase.rest.RESTServer.main
> 423 try {
> 424 server.run();
> 425 server.join();
> 426 } catch (Exception e) {
> 427 System.exit(1);
> 428 }
> {code}
> We need print the failure message to help user config the system.
