Subject [jira] [Comment Edited] (YARN-5448) Resource in Cluster Metrics is not sum of resources in all nodes of all partitions
Date Fri, 29 Jul 2016 08:15:21 GMT

As per discussion with [~wangda], we had considered following options :
# *Metrics overview table* needs to show the resources of all the active NM's 
# *parititon-by-queue-hierarchy chart*, we can show non-usable partition (with some NM's)
, and under the partition show "the partition is not assigned to any queue" Or other option
is to show Partition resource in different font/color  (red) and having tool tip as "the partition
is not assigned to any queue" 
Thoughts ?

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: capacity scheduler, resourcemanager, webapp
>    Affects Versions: 2.7.2

> 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.
