WebDriver grid configuration throws error - selenium

Question

I have the following setup:
I am running a grid hub on my local pc with the following config:
java -jar selenium-server-standalone-2.42.0.jar -role hub -grid1Yml grid_configuration.yml
the config looks like this:
hub:
port: 4444
remoteControlPollingIntervalInSeconds: 180
sessionMaxIdleTimeInSeconds: 300
newSessionMaxWaitTimeInSeconds: 600
environments:
- name: "Firefox on Windows"
browser: "*firefox"
...
I am starting the node via
java -jar selenium-server -standalone-2.42.0.jar -role node -hub http://localhost:4444/grid/register -port 8888 -browser "browserName=Firefox on windows,maxInstances=1,version=1,platform=WINDOWS"
My Test setup looks like this:
public static void main(String[] args) throws MalformedURLException {
System.setProperty("webdriver.ie.driver","C:\\IEDriverServer.exe");
DesiredCapabilities cap = DesiredCapabilities.firefox();
cap.setBrowserName("*firefox");
RemoteWebDriver remoteWebDriver = new RemoteWebDriver(new URL("http://127.0.0.1:4444" + "/wd/hub"), cap);
}
If i run my test i get the following error:
Exception in thread "main" org.openqa.selenium.WebDriverException: Error forwarding
the new session webdriver new session JSON response body did not contain a session ID
Command duration or timeout: 946 milliseconds

In the webdriver node i get the important error:
Exception: The path to the driver executable must be set by the webdriver.ie.driver system property...
I have set this property via java and in my windows environment. I do not know why i am still getting this error message.
UPDATE
If i use the grid2 config file (json), how is it possible to set an individual browser by name on each host.
Example:
hub:
port: 4444
remoteControlPollingIntervalInSeconds: 180
sessionMaxIdleTimeInSeconds: 300
newSessionMaxWaitTimeInSeconds: 600
environments:
- name: "MyFireFox on MyMachine1"
browser: "*firefox"
- name: "MyFireFox on MyMachine2"
browser: "*firefox"
If i use this hub config i can start a node by saying it is a "MyFireFox on MyMachine1" Browser. The attribute browser is telling webdriver to use Firefox on the system
If i now use the grid2 config json, i have the following
{
"capabilities":
[
{
"browserName": "MyFireFox on MyMachine1",
"platform": "WINDOWS",
"maxInstances": 1
},
but this will not work, because i think the browserName is what browser was in grid1 config.

Answer 1

this is config from my .bat files. also, why do you change your node port to 8888 ? try to remove '-port 8888' and check again
for hub:
java -jar path_to_selenium-server-standalone-2.41.0.jar -role hub
for node:
java -jar path_to_selenium-server-standalone-2.41.0.jar -role node -hub http://localhost:4444/grid/register -browser browserName=firefox, platform=WINDOWS
here is my json and bat file which 100% works
{
"capabilities":
[
{
"browserName": "firefox",
"platform": "WINDOWS",
"maxInstances": 1
},
{
"browserName": "internet explorer",
"version": "10",
"platform": "WINDOWS",
"maxInstances": 1
}
],
"configuration":
{
"nodeTimeout":120,
"port":5555,
"hubPort":4444,
"hubHost":"192.168.3.104",
"nodePolling":2000,
"registerCycle":10000,
"register":true,
"cleanUpCycle":2000,
"timeout":30000,
"maxSession":1
}
}
and bat to start node from json
java -jar selenium-server-standalone-2.41.0.jar -role node -nodeConfig nodeConfig_win7.json
also in system PATH you should add path to folder with drivers for browsers
