can't run CHROME using selenium webdriver remote

Question

I am using python with selenium webdriver to run and automate test cases on a grid. I am able start the FIREFOX browser with some warning messages on both hub and node, but it works fine. But the issue is starting the same web application using CHROME. I tried everything possible, but no help. Whenever I have to start off with the CHROME browser locally, I used to run the chromedriver.exe to start the app. but I don't know how to parse the chromedriver.exe remotely to start the same app there. I have even tried installing and started running the chromedriver on the node and checked f it starts running but it was of no help.And have set the system property as well...

java -jar ./selenium-server-standalone-2.35.0.jar - Dwebdriver.chrome.driver='/opt/drivers/chromedriver' -role webdriver -hub  http://192.168.1.10:4444/grid/register -port 5566 -browser browserName=chrome

output:

The issue seems that you're try to open the file pointing in the wrong location:

 WebDriverException: Message: The driver executable does not exist: C:\\Users\\user\\'C:\\Users\\user\\Desktop\\chromedriver.exe' Stacktrace: 

btw isn't clear why you're trying to start chromedriver with java if you're using python..

If you're using python you can check this: test suite python - webdriver
