Subject [jira] [Commented] (YARN-6651) Flow Activity should specify 'metricstoretrieve' in its query to ATSv2 to retrieve CPU and memory
Date Wed, 15 Nov 2017 14:11:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16253496#comment-16253496

Sunil G commented on YARN-6651:
-------------------------------

[~akhilpb], I discussed with [~rohithsharma] also.

We can use "?metricstoretrieve=YARN_APPLICATION_CPU,YARN_APPLICATION_MEMORY" instead of "fields=ALL"
so that CPU and MEMORY could retrieved and updated in FLOW RUNS page.

YARN-6653 is similar but was specific to apps CPU and MEMORY usage, We can use same filter
to query metrics for an app in a FLOW RUN

> When you click on Flow Acitivity => \{a flow\} => flow runs, the web server sends
a REST query to ATSv2 TimelineReaderServer, but it does not include a query param 'metricstoretrieve"
to get any metrics back.
> Instead, we should add '?metricstoretrieve=YARN_APPLICATION_CPU,YARN_APPLICATION_MEMORY'
to the query to get CPU and MEMORY back.
