---------------------------------

             Summary: Service to report REEF events
                 Key: REEF-714
                 URL: https://issues.apache.org/jira/browse/REEF-714
             Project: REEF
          Issue Type: New Feature
          Components: REEF
            Reporter: Geon Woo Kim
            Assignee: Geon Woo Kim
             Fix For: 0.13


Control plane events, such as {{AllocatedEvaluator}} and {{ActivatedContext}},  can easily be tracked by adding {{EventListener}} s to {{DriverConfiguration}} without disturbing the application. It would be good to make a Service that listens to and reports the events. Also, the Service can be enhanced to work as a general profiler by adding more event types for profiling.

This service 
 1) should be integrated with existing REEF applications.
 2) should report events in a well-defined format.
 3) can print the events to the file system.
 4) can report the events to an external web server using RESTful API.

This can be used to implement a realtime observation web UI like [spark-spree|http://www.hammerlab.org/2015/07/25/spree-58-a-live-updating-web-ui-for-spark/].
