Selenium Grid cannot able create a new session error is showing

Question

I am learning Selenium Grid and beginner for it.I setup my hub by using command:- java -jar selenium-server-standalone-3.3.0.jar -role hub and node is setup by using command:- java -jar selenium-server-standalone-3.3.0.jar -role webdriver -hub IP_of_hub:4444/grid/register -port 1234

Than i created a java project and created a class and write the down the code

import junit.framework.Assert;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.xerces.util.URI.MalformedURIException;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;

    public class selGrid {

        WebDriver driver;
        String base_url,node_url;

        @BeforeTest
        public void setUp() throws MalformedURLException{
            System.setProperty("webdriver.gecko.driver","C://Users//Administrator//Downloads//geckodriver.exe");
            base_url="http://newtours.demoaut.com";
            node_url="http://localhost:1234/wd/hub";
            DesiredCapabilities capability=DesiredCapabilities.firefox();
            capability.setBrowserName("firefox");
            capability.setPlatform(Platform.WINDOWS);

            driver=new RemoteWebDriver(new URL(node_url),capability);
        }
        @AfterTest
        public void afterTest()
        {
            driver.quit();
        }
         public void simpleTest()
        {
            driver.get(base_url);
            Assert.assertEquals("Welcome", driver.getTitle());
        }


      }}

And run it is as TestNGand in the console below text is showing

Did you set the path to the driver, like the stack trace suggests ? — Tim, Apr 03 '17 at 10:44
Read this: http://stackoverflow.com/questions/38676719/selenium-using-java-the-path-to-the-driver-executable-must-be-set-by-the-webdr — Tim, Apr 03 '17 at 10:47
@Tim i set the path, now Firefox is opening but to next process it is not proceeding Thanks for help. — Priti Andhale, Apr 03 '17 at 11:43
Well, you did not post your actual @Test code. Also, before using the grid right away, you should try to make your test work locally. Then only should you try to run it on the grid. — Tim, Apr 03 '17 at 11:47
only this part of code is commented @Test public void simpleTest() { driver.get(base_url); Assert.assertEquals("Welcome", driver.getTitle()); } — Priti Andhale, Apr 03 '17 at 11:53
You should edit your question with this code. Also, when / where do you set the actual URL ? What error message do you get ? — Tim, Apr 03 '17 at 11:56
But i am facing issue FAILED CONFIGURATION: @BeforeTest setUp org.openqa.selenium.SessionNotCreatedException: Unable to create new remote sessoion. — Priti Andhale, Apr 03 '17 at 11:57
You should update your question with the current stack trace. Did you register your node to the hub ? (Are those running on the same machine ?) I find your code a bit confusing: Shouldn't "node_url" be called "hub_url" ? Also, each node needs the driver. — Tim, Apr 03 '17 at 12:04
@Tim I updated question. I register my node to hub.Both node and hub are on same machine( IP of machine is replaced by localhost). — Priti Andhale, Apr 03 '17 at 12:22
Does your test work locally ? (without the Grid configuration) — Tim, Apr 03 '17 at 12:36
@Tim I resolved issue it is firefox version issue. Thank you for suggesting me the path set — Priti Andhale, Apr 03 '17 at 12:52
In that case, you should answer your own question and accept it, so others know. If you think your solution can prevent others from having to ask a new question, be as precise as you can :) — Tim, Apr 03 '17 at 13:03

Set the path of geckodriver and use the latest version of firefox(or one can check compatible firefox for standalone server). Now I used firefox ver 52.0.2 and standalone server is 3.3.0
