bq. But resource allocation is only some % of X. (not for full cluster).
Suppose the node is mapped to a Exclusive Partition and users are asking for
*other partitions* then irrespective of the configuration of accesibiltiy of
this partition to any queue, *resource allocation is only some % of X*.
And suppose users tries to submit the app when the partition is *not* mapped
then anyway Application Submission fails with appropriate exception. So it
will not be like a surprice for the admin or its not something which will get
unnoticed.
bq. But I am not sure how these labels can be visible enough to user from
scheduler UI to convey the issue. Could you share how it may come.
Was planning to show the Partition information in different color (red) with a
tooltip indicating the information "the partition is not assigned to any leaf
queue"
> Resource in Cluster Metrics is not sum of resources in all nodes of all
> partitions

> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacity scheduler, resourcemanager, webapp
> Affects Versions: 2.7.2
> Reporter: Naganarasimha G R
> Assignee: Naganarasimha G R
> Attachments: NodesPage.png, schedulerPage.png

> Currently Resource info from Cluster Metrics are got from Queue Metrics's
> *available resource + allocated resource*. Hence if there are some nodes
> which belongs to partition but if that partition is not associated with any
> queue then in the capacity scheduler partition hierarchy shows this nodes
> resources under its partition but Cluster metrics doesn't show.
> Apart from this in the Nodes page too Metrics overview table is shown. So if
> we show Resource info from Queue Metrics User will not be able to co relate
> it. (have attached the images for the same)
> IIUC idea of not showing in the *Metrics overview table* is to highlight that
> configuration is not proper. This needs to be some how conveyed through
> parititon-by-queue-hierarchy chart.
