Zhijie Shen commented on YARN-3984: ----------------------------------- In fact, metric has the same problem, but it may be still okay to ignore a metric without any data. > Rethink event column key issue > ------------------------------ > > Key: YARN-3984 > URL: https://issues.apache.org/jira/browse/YARN-3984 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Zhijie Shen > Assignee: Vrushali C > Fix For: YARN-2928 > > > Currently, the event column key is event_id?info_key?timestamp, which is not > so friendly to fetching all the events of an entity and sorting them in a > chronologic order. IMHO, timestamp?event_id?info_key may be a better key > schema. I open this jira to continue the discussion about it which was > commented on YARN-3908. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
