[jira] [Commented] (YUNIKORN-165) API response fields can be returned as proper data structure rather than free text
[ https://issues.apache.org/jira/browse/YUNIKORN-165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17501170#comment-17501170 ]
Wilfred Spiegelenburg commented on YUNIKORN-165:
------------------------------------------------
The units were mentioned in an off-line discussion. It hooks into the way K8s represents resources and how we use that. YuniKorn has made the ambiguous decision to use *MB* for memory and *milli* for cpu. See YUNIKORN-1105 for the impact.
I do not think we should move to integers in the representation. We should stick closer to what K8s does.

> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - common, webapp
> Reporter: Ayub Pathan
> Priority: Critical
>
> For most of the APIs, some of the fields are recorded as free text, this can be improved by sending them as proper data structure like map etc. This helps in easy consumption of the REST aPI response.
> For example:
> * Some fields from Apps API like resource,usedResource, partition can be returned as maps..
> {noformat}
> {
> "allocations": [
> {
> "allocationKey": "1e5225f7-4d60-400f-8b9b-5b7027b4c394",
> "allocationTags": null,
