Andrew Ash created SPARK-3428:
---------------------------------

             Summary: TaskMetrics for running tasks is missing GC time metrics
                 Key: SPARK-3428
                 URL: https://issues.apache.org/jira/browse/SPARK-3428
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 1.1.0
            Reporter: Andrew Ash
            Assignee: Sandy Ryza


SPARK-2099 added the ability to update helpful metrics like shuffle bytes read/written on
the webui via a periodic heartbeat from executors.  It omitted GC time metrics though.

This ticket is for including GC times in the heartbeats.

See the updateAggregateMetrics method here:
