Andras Gyori commented on YARN-10657:
-------------------------------------
Thank you [~zhuqi] for working on this issue. After analysing the affected code
I have the following concerns:
* The current approach is not a true node label support, it is still using a
single maxApplication value for all nodeLabels. I am not sure if the current
approach would make anything better, but could easily create confusion.
* To be able to support true nodeLabels, one would need to store a
maxApplication value for each nodeLabel (eg. in a Map). However, as I see it,
on application submission, where this maxApplication is retrieved and used as
some sort of validation in the queue, we do not have a reference to the node
label. I think it would involve too much work for a feature that is not a high
priority item.
> We should make max application per queue to support node label.

> As we discussed in above comment:
> We should deep into the label related max applications per queue.
> I think when node label enabled in queue, max applications should consider
> the max capacity of all labels.
