Not able to implement selenium grid

Question

Below is my code which I am using to pass browser, node and hub port to launch browser and execute the tests but i get exception although I am able to set up selenium server. I paste error below of the code too. I use mac book, Selenium 3.4, Firefox 55 and Gecko 0.18.0

public synchronized WebDriver setUp(String browser, String 
nodePort, String hubPort) throws MalformedURLException{

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setPlatform(Platform.MAC);
capabilities.setCapability(CapabilityType.BROWSER_NAME, browser);
capabilities.setCapability(ForSeleniumServer.PROXYING_EVERYTHING, 
true);
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
capabilities.setCapability(CapabilityType.SUPPORTS_ALERTS, true);
capabilities.setCapability(CapabilityType.SUPPORTS_JAVASCRIPT, 
true);

if(browser.equals("firefox"))
    System.setProperty("webdriver.gecko.driver", 
System.getProperty("user.dir")+"//geckoDriver//geckodriver");
else if(browser.equals("chrome"))
    System.setProperty("webdriver.chrome.driver", 
System.getProperty("user.dir")+"//chromeDriver//chromeDriver");
driver = new RemoteWebDriver(new 
URL("http://localhost:"+nodePort+"/wd/hub"), capabilities);
driver.get("https://www.bookbaby.com");
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
System.out.println(driver.toString());
return driver;

Error is

please set environment variable webdriver.gecko.driver in your machine and its value.

or you can pass the parameter webdriver.gecko.driver while starting your hub or registering your node. like

java -Dwebdriver.gecko.driver="path to the gecko driver" {jar} -role node/hub

the way i set up wont work?System.setProperty("webdriver.gecko.driver", System.getProperty("user.dir")+"//geckoDriver//geckodriver"); – Ref Sep 12 '17 at 13:48
it will not work if you are executing on selenium grid. it will work without grid. – Murthi Sep 12 '17 at 13:50

Firstly say the issue in your code, if you want to use the selenium server/grid please specify the webdriver path in command line when start selenium server,rather than specify by code.
so below code is unnecessary, they are only necessary when you choose run test not using selenium server/grid, we call it 'directConnect' (your script communicate directly with webdriver.exe)

if(browser.equals("firefox"))
        System.setProperty("webdriver.gecko.driver", 
    System.getProperty("user.dir")+"//geckoDriver//geckodriver");
    else if(browser.equals("chrome"))
        System.setProperty("webdriver.chrome.driver", 
    System.getProperty("user.dir")+"//chromeDriver//chromeDriver");

register node to hub argument example to specify webdriver.exe path:

java
-Dwebdriver.chrome.driver=C:\selenium\chromedriver_2.32.exe 
-Dwebdriver.gecko.driver=C:\selenium\geckodriver-v0.18.0.exe 
-jar C:\selenium\selenium-server-standalone-3.4.0.jar 
-role node
-port 4446

Reminder: please check the standalone.jar, specified webdriver.exe and browser on node are compatible with each other, otherwise the node will fail to launch browser in testing.

Thanks for your help. Now I run this command and works for firefox but not for chrome,any idea . java -Dwebdriver.chrome.driver=Users/username/chromeDriver/chromedriver -Dwebdriver.gecko.driver=/Users/username/gecko_driver/geckodriver -jar /Users/username/selenium-server/selenium-server-standalone-3.5.3.jar -role node -port "+nodePort+" -hub http://localhost:"+hubPort+"/grid/register — Ref, Sep 12 '17 at 16:02
please check the chromedriver compatibel with your chrome browser, my chrome version is 60 and chromedriver is 2.30 — yong, Sep 12 '17 at 16:06
