Subject [jira] [Commented] (MAPREDUCE-6424) Store MR counters as timeline metrics instead of event
Date Fri, 29 Apr 2016 20:19:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15264670#comment-15264670

Naganarasimha G R commented on MAPREDUCE-6424:
----------------------------------------------

Well actually i was more looking at an API like {{HistoryEvent.getTimelineEntitiesToPublish}}
which returns array of *TimelineEntities* which can be taken by JobHistoryEventHandler and
directly published using timelineclient

> In MAPREDUCE-6327, we make map/reduce counters get encoded from JobFinishedEvent as timeline
events with counters details in JSON format. 
> We need to store framework specific counters as metrics in timeline service to support
query, aggregation, etc.
