   @dongjoon-hyun Yes, it was also failed in 4U6G. My previous env have 8U16G, so it passed.
   
   Cluster have 4U means we can only use about 3U for resources.
   
   Also means we can only submitted <= 2 PI jobs (1 driver + 1 executor) in parallel **if no resource control**. Otherwise, all drivers are running to occupy all resource, executors will pending, then stack.
