[jira] [Created] (YARN-3981) support timeline clients not associated with an application

Sangjin Lee created YARN-3981:
---------------------------------

             Summary: support timeline clients not associated with an application
                 Key: YARN-3981
                 URL: https://issues.apache.org/jira/browse/YARN-3981
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Sangjin Lee


In the current v.2 design, all timeline writes must belong in a flow/application context (cluster + user + flow + flow run + application).

But there are use cases that require writing data outside the context of an application. One such example is a higher level client (e.g. tez client or hive/oozie/cascading client) writing flow-level data that spans multiple applications. We need to find a way to support them.
