Wangda Tan commented on YARN-5256:
----------------------------------
[~Naganarasimha],
Sorry for the late comment, I totally missed this JIRA previously.
I just quickly discussed with [~sunilg] about this. Do you think if adding the
new object is necessary? I think it might be better to reuse the existing
object ({{NodeLabelInfo}}).
By default we will return resources of the label, such as total/used resource.
And nodes associated to the label will be returned only if requested.
So we will add used/total resource and list of nodeIds to {{NodeLabelInfo}}.
For the REST end point, what we can do is:
- For the ("/get-node-labels") call, add an optional parameter to indicate if
we need to return associated nodes.
- Add a new ("/get-node-labels/{node-label}") call, only return information of
a given label, and have an optional param to indicate if we need to return
associated nodes.
- In above APIs, return used/total resource.
Sounds like a plan?
