Bibin Chundatt commented on YARN-10738:
---------------------------------------

[~zhuqi] I think this should be part of the *MultiNodeLookupPolicy * 
implementation.


> When multi thread scheduling with multi node, we should shuffle to prevent 
> hot accessing nodes.

> 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.
