title: Spark limit number of executors per service
body: <p>We are using Spark streaming (java) for real time computation. Deployment has 6 node spark cluster (config setting is for 200 executors across nodes). </p>
  
  <p>Currently there is one service which was publishing events in Rabbitmq queue. Now we are planning to add two more services. In case I create spark receiver per queue, is it possible to limit maximum number of executors that can serve one service in case of load scenario (say max limit 50%. So in above case at max 100 executors can serve streams receiving from service/receiver)? </p>
  
  <p>Thanks
