-----------------------------------------
Hi [~Feng Yuan],
bq. think it means if queue A`s partition x is used up,app can get containers
from DEFAULT_PARTITION? Do i misstake?
i think your understanding here is wrong, apps with requests on
DEFAULT_PARTITION can make use of resources in NonExclusive partitions only
when Nonexclusive parttion resources are free. But resource requests for
specific partition cannot be allocated to Default Partition. And neither in 2.6
we supported it !
> Labeled apps cant use <DEFAULT_PARTITION> resources in 2.8

> Queue A use partition X,When x is used up,app cant get resource from
> <DEFAULT_PARTITION>.
> I find this behavior is different from 2.7.x.Also i find this in the document
> of 2.7.2 as blew:
> "All queues can access to nodes without
> label"--https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/NodeLabel.html
> I think it means if queue A`s partition x is used up,app can get containers
> from DEFAULT_PARTITION? Do i misstake?
> And I can confirm my configs is correct.Because i can run profectlly in 2.7.x
> use this configation too.
> I have observed this in 2.8: "<DEFAULT_PARTITION> is marked as
> <ECLUSIVE_PARTITION>" in webui.Is this the reason?
