This configuration only applies when HAWQ's YARN queue is busy, and HAWQ makes the YARN queue overuse its resources. The default value is 10, which means HAWQ will return 10% of acquired YARN containers by pausing the allocation of resources to HAWQ queries. In a typical deployment, you do not need to modify the default value of this parameter.
