Root cause analysis
To start the selenium grid, you need selenium standalone jar. That has to be executed at the local machine, or at the machine where you want to host your hub on.
For this, you need to make sure the command you are executing should be correct and complete. Recheck the above command I have added.
The command is not specifying any role, whether the Selenium grid should treat this instance as a Node or Hub.
Solution
java -jar selenium-server-standalone-2.41.0.jar -role hub

Specifying the role as the hub will solve this issue, you can make this instance as Node also for this you have to make sure that the -role parameter should get a Node as a role.
