> When refactor the update logic in YARN-10504 .
> The update max applications based abs/cap is wrong, this should be fixed,
> because the max applications is key part to limit applications in CS.
> For example:
> When adding a dynamic queue, the other children's max app of parent queue are
> not updated correctly:
> !image-2021-02-20-15-53-51-099.png|width=639,height=509!
> The new added queue's max app will updated correctly:
> !image-2021-02-20-15-55-44-780.png|width=542,height=426!
