[jira] [Commented] (YARN-3362) Add node label usage in RM
CapacityScheduler web UI
[ https://issues.apache.org/jira/browse/YARN-3362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14366191#comment-14366191 ]
Wangda Tan commented on YARN-3362:
----------------------------------
My proposal is:
For now, RM CapacityScheduler UI looks like
{code}
+ root [==========================] 50% used
+ a [=======================================] 75% used
- a1 [=================] 30% used
---------------------------------------------
| Queue Metrics Table |
|--------------------------------------------|
| metrics1 | value1 |
| metrics2 | value2 |
| metrics3 | value3 |
| metrics4 | value4 |
----------------------------------------------
+ b [...]
+ c [...]
{code}
We can add one more hierarchy above queue's hierarchy, which are labels can be accessed and/or labels are being used by the queue, which can looks like
{code}
+ label_x [=====================] 30% used
+ root [=====================] 30% used
+ a [=======================================] 75% used
+ a1 [=================] 30% used
---------------------------------------------
| Queue Metrics Table (For label_x) |
|--------------------------------------------|
| metrics1 | value1 |
| metrics2 | value2 |
| metrics3 | value3 |
| metrics4 | value4 |
----------------------------------------------
+ label_y
+ root [...]
+ ...
+ label_z
+ root [...]
+ ...
+ no_label
+ root [...]
+ ...
{code}
To make it backward compatible, when there's no label in the system, it will not show "label-bar", and root is still "root-queue".
Please feel free to share your ideas on this!
