hello @rrrajat111 - welcome to the community. So from what you are describing, it seems that you have a RM Server process that is either hung or just so massive that it will run forever. Normally RM Server is for deployment solutions; have you run this in Studio beforehand? Have you tried reducing the size of your data set and running it?
You actually can abort the process on the server (on Process-Scheduler page) and then click on the Log icon at the right, there you will see at which exacly operator it was stuck when you aborted it. This might give you a clue.
But I also agree with @sgenzer that you should try running it locally first.
