[jira] [Commented] (YARN-10657) We should make max application per
queue to support node label.
[ https://issues.apache.org/jira/browse/YARN-10657?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17315348#comment-17315348 ]
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.

> 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.
