Subject [jira] [Commented] (YARN-3041) create the ATS entity/event API
Date Fri, 30 Jan 2015 04:23:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-3041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14298182#comment-14298182

Zhijie Shen commented on YARN-3041:

[~rkanter], thanks for the patch. I've just attached my data model proposal in the umbrella
jira. It seems that we're almost on the same page.

Several major differences I've noticed:

1. Metric and event are separate from entity as they are compound too.
2. I suggest using more generalized in/outbound relationship instead of parent-child one.
For example, multiple vertex in a dag.
3. I'm wondering if cluster and user are really necessary to be standalone entity instead
of one field of an entity.
