[jira] [Comment Edited] (YARN-8964) UI2 should use
clusters/{cluster name} for all ATSv2 REST APIs
[ https://issues.apache.org/jira/browse/YARN-8964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16694411#comment-16694411 ]

v2 patch incorporates cluster-id changes and ATSv2 log URL changes.
One thing I noted that {{yarn.log.server.web-service.url}} returns {{http://<ats-host>:<port>/ws/v1/applicationhistory}} for old clusters. But this might return {{http://<ats-host>:<port>/ws/v1/applicationlogs}} for new clusters which has ATSv2 log servlet changes. Please note the difference in namespaces between ATSv1.5 and ATSv2. Because of this namespace difference, I think dynamically fetching and setting the log-url in URL makes difficult.
Please share your thoughts.
Note: v2 patch does not yet support dynamic config of log URL. Please share your thoughts on the above issue and will update the new patch accordingly.

> UI2 makes a REST call to TimelineReader without cluster name. It is advised to make a REST call with clusters/{cluster name} so that remote TimelineReader daemon could serve for different clusters.
> *Example*:
> *Current*: /ws/v2/timeline/flows/
> *Change*: /ws/v2/timeline/*clusters/\{cluster name\}*/flows/
> *yarn.resourcemanager.cluster-id *is configured with cluster. So, this config could be used to get cluster-id
