Selenium Grid +Error forwarding the new session Empty pool of VM for setup Capabilities

问题

I am trying a POC on selenium grid. I am receiving this error :

Error forwarding the new session Empty pool of VM for setup Capabilities [{browserName=chrome, version=47, platform=WIN8_1}]

Below is the code :

BeforeTest
    public void setup() throws MalformedURLException{
        nodeURL="http://localhost:4444/wd/hub";
        DesiredCapabilities capabilities = DesiredCapabilities.chrome();
        capabilities.setBrowserName("chrome");
        capabilities.setVersion("47");
        capabilities.setPlatform(Platform.WIN8_1);
        extent = new ExtentReports("./extentReport.html",true,DisplayOrder.NEWEST_FIRST);
        System.setProperty("webdriver.chrome.driver", "<path>\\chromedriver.exe");
        driver = new RemoteWebDriver(new URL(nodeURL),capabilities);
        //driver = new ChromeDriver(capabilities);
        driver.manage().window().maximize();
        driver.get("http://www.qaonlinetraining.com");
    }

I just did a small tweak.

1). I launched the command prompt in "admin mode". 2). Gave the java path as "cd C:\Program Files (x86)\Java" in it 3). Then ran the command as "java -jar selenium-server-standalone-3.0.1.jar" without specifying any role

and Vollaaaa...it got fixed...!!!

Thanks to all of you for your help...Was after this error for last 3 days...a great relief must say.. :-)

Launch Selenium-server-standalone with below commands as hub and node.

For hub:

java -jar selenium-server-standalone-2.48.2.jar -role hub

For node (Chrome):

java -jar selenium-server-standalone-2.48.2.jar -role node  -hub http://localhost:4444/grid/register -browser "browserName=chrome,maxinstance=1,platform=WINDOWS" -Dwebdriver.chrome.driver=C:\Selenium\chromedriver.exe

May be you have to get rid of -role hub option while setting up the node. Look at the discussion in this link.

Note: Launch the command prompt in admin mode.
