             Summary: Decide detailed package structures for timeline service 
v2 components
                 Key: YARN-3166
             Project: Hadoop YARN
          Issue Type: Task
            Reporter: Li Lu

Open this JIRA to track all discussions on detailed package structures for 
timeline services v2. This JIRA is for discussion only so I don't think it 
should have any assignees. 

For our current timeline service v2 design, aggregator (previously called 
"writer") implementation is in hadoop-yarn-server's:

In YARN-2928's design, the next gen ATS reader is also a server. Maybe we want 
to put reader related implementations into hadoop-yarn-server's:

Both readers and aggregators will expose features that may be used by YARN and 
other 3rd party components, such as aggregator/reader APIs. For those features, 
maybe we would like to expose their interfaces to hadoop-yarn-common's 

Let's use this JIRA as a centralized place to track all related discussions.
