Subject [jira] [Commented] (YARN-5256) [YARN-3368] Add REST endpoint to support detailed NodeLabel Informations
Date Fri, 09 Sep 2016 07:53:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15476251#comment-15476251

Sunil G commented on YARN-5256:

Hi [~ajithshetty] and [~Naganarasimha Garla]

We can make to trunk. I think thats fine..

bq.2. When labels are null, can we return all the labels details.?
We already have {{@Path("/get-node-labels")}}. But with out resource/node info. Are we looking
a case to improve {{get-node-labels}} to have information like resource/nodes. Its better
we make use of existing api to get more information. Thoughts? We can do here also, but it
may become slightly duplicated i guess.

bq.3. Instead of one label, can we accept set of labels.?
For all labels, we can get the information based on consensus from previous comment. Do you
see use case to get this stats info for few labels together in single request. To do this,
we need to change response to a Map<LabelName, LabelInfo>. From UI perspective, we wanted
to get info per-label stats to show detailed node-label page. and All labels info was retrieved
by {{get-node-labels}}. It will be great if you could share usecase also.
