Gengliang Wang created SPARK-25712:
--------------------------------------

             Summary: Improve usage message of start-master.sh and start-slave.sh
                 Key: SPARK-25712
                 URL: https://issues.apache.org/jira/browse/SPARK-25712
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.4.0
            Reporter: Gengliang Wang


Currently if we run 
```
./sbin/start-master.sh -h
```
We get
```
Usage: ./sbin/start-master.sh [options]
18/10/11 23:38:30 INFO Master: Started daemon with process name: 33907@C02TL2JZGTF1
18/10/11 23:38:30 INFO SignalUtils: Registered signal handler for TERM
18/10/11 23:38:30 INFO SignalUtils: Registered signal handler for HUP
18/10/11 23:38:30 INFO SignalUtils: Registered signal handler for INT

Options:
  -i HOST, --ip HOST     Hostname to listen on (deprecated, please use --host or -h) 
  -h HOST, --host HOST   Hostname to listen on
  -p PORT, --port PORT   Port to listen on (default: 7077)
  --webui-port PORT      Port for web UI (default: 8080)
  --properties-file FILE Path to a custom Spark properties file.
                         Default is conf/spark-defaults.conf.
```
We can filter out some of useless output.
