Selenium 3.0 does not run on firefox on the grid - selenium-webdriver

Question

When I run my scripts using Selenium 3.0 on the grid, only firefox instances open and nothing happens.
My setup is like this:
Selenium - 3.0.0
Selenium Grid - hub and node started using Selenium 3.0.0 and with below options:
hub -
java -jar selenium-server-standalone.jar -role hub -timeout 300000
node -
java -Dwebdriver.gecko.driver=C:\Grid2\geckodriver-v0.11.1-win64\geckodriver.exe -jar selenium-server-standalone.jar -role node -hub http://localhost:4444/grid/register -port 5556 -nodeConfig se2config.txt

}
Firefox version - 47.0.2
Added geckodriver.exe path to PATH variable and also in the code using:
System.setProperty("webdriver.gecko.driver","<path>")
The scripts run fine locally, but when run on the grid, it just launches the firefox browser and does not do anything.
Following are the node logs:

The scr
I run the scripts from my local system and it gets executed on the grid node.
1.So what other changes or additions do I make to run tests on the grid.
2.Also, if I were to run my tests using jenkins, so since the code will be built on the jenkins node, how can I set the -Dwebdriver path for node, does it have to be the path of geckodriver on the jenkins slave or of that of the grid node.
