Verified with tpcds q95 on a gpu node with below configurations:

Started 2 cpu workers and 1 gpu worker using the script above. During
runtime there's one executor started on each worker. Only the 40 tasks of stage
40 were scheduled to the executor on the gpu worker, all other tasks were
scheduled to the executor on the 2 cpu workers. Next will try it on a real
mixed cpu/gpu cluster.
