Unable to launch firefox with selenium grid 3.0.1 gecko driver 0.11.1 firefox 50.0.1 - selenium

Question

Trying to launch firefox with selenium grid is through exception as below:
org.openqa.selenium.sessionnotcreatedexception
Code I am using is as below:
if(useRemoteWebDriver){
URL seleniumGridURL = new URL(System.getProperty("gridURL"));
String desiredBrowserVersion = System.getProperty("desiredBrowserVersion");
String desiredPlatform = System.getProperty("desiredPlatform");
if (!desiredPlatform.isEmpty())
if ((null != desiredPlatform)) {
desiredCapabilities.setPlatform(Platform.valueOf(desiredPlatform.toUpperCase()));
}
if (null != desiredBrowserVersion && !desiredBrowserVersion.isEmpty()){
desiredCapabilities.setVersion(desiredBrowserVersion);
}
webDriver = new RemoteWebDriver(seleniumGridURL, desiredCapabilities);
}else{
webDriver = selectedDriverType.getWebDriverObject(desiredCapabilities);
}
and I am trying to run it from command line using
mvn clean install -Dremote=true -DseleniumGridURL=http://localhost:5555/wd/hub -Dbrowser=firefox -Dwebdriver.gecko.driver="E:\GeckoDriver\geckodriver.exe" -DbrowserVersion="50.0.1"
this is giving me the following exception
org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{marionette=true, binary=C:\Program Files (x86)\Mozilla Firefox\firefox.exe, browserName=firefox, version=50.0.1, platform=ANY}], required capabilities = Capabilities [{}]
