Hitesh Shah commented on YARN-2928: ----------------------------------- bq. We should have such a configuration that disables the timeline service globally. Please explain what "globally" means. bq. Can it be handled as a "flow of flows" as described in the design? For instance, tez application <-- hive queries <-- YARN apps? Or does it not capture the relationship? Not sure I understand clearly as to how the relationship is captured. Consider this case: There are 5 hive queries: q1 to q5. There are 3 Tez apps: a1 to a3. Now, q1 and q5 ran on a1, q2 ran on a2 and q3,q4 ran on a3. Given q1, I need to know which app it ran on. Given a1, I need to know which queries ran on it. Could you clarify how this should be represented as flows? > Application Timeline Server (ATS) next gen: phase 1 > --------------------------------------------------- > > Key: YARN-2928 > URL: https://issues.apache.org/jira/browse/YARN-2928 > Project: Hadoop YARN > Issue Type: New Feature > Components: timelineserver > Reporter: Sangjin Lee > Assignee: Sangjin Lee > Priority: Critical > Attachments: ATSv2.rev1.pdf, ATSv2.rev2.pdf, Data model proposal > v1.pdf > > > We have the application timeline server implemented in yarn per YARN-1530 and > YARN-321.
