> user can set the minimum YARN container water level through guc hawq_rm_min_resource_perseg. 
> 1) If the segment capacity is smaller than expected level, this water level is lowered down;
> 2) If the queue capacity can not make each segment have at least hawq_rm_min_resource_perseg YARN containers, this water level is lowered down.
> This improvement can make HAWQ able to dynamically fit the changing YARN cluster and avoid user wrong config caused unexpected behaviors.
