Qi Zhu updated YARN-10738:
--------------------------
Description:
Now the multi threading scheduling with multi node is not reasonable.
In large clusters, it will cause the hot accessing nodes, which will lead the
abnormal boom node.
Solution:
I think we should shuffle the sorted node (such the available resource sort
policy) with an interval.
I will solve the above problem, and avoid the hot accessing node.
