Hi,
I have a running instance of the Selenium Grid plugin running on Jenkins
LTS 1.480.1.
* I've configured the grid to use a chrome browser:
> {seleniumProtocol=WebDriver, platform=LINUX, browserName=chrome,
> maxInstances=5, jenkins.nodeName=CentOS 6 Java 7, version=24.0}
* I've installed the chromedriver on my remote machine at
/usr/local/jenkins/tools/chrome/chromedriver
* I've installed chrome on the remote machine at /usr/bin/google-chrome
* I used the Firefox Selenium IDE to create a test case and tweaked it a
bit for RemoteWebDriver

Specifically, I'm confused by the error. I've read the documents that the
error mentions and I thought I was specifying the system property of
webdriver.chrome.driver. Has anyone ran into this? Can anyone offer any
help for my understanding of why I can't get chrome to work using the
RemoteWebDriver and the Selenium Grid plugin?
Thanks for looking,
BH
