             Summary: Allow ExecutorMetricsUpdate events to be logged to the event log with sampling
                 Key: SPARK-23353
                 URL: https://issues.apache.org/jira/browse/SPARK-23353
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.2.1
            Reporter: Lantao Jin


[SPARK-22050|https://issues.apache.org/jira/browse/SPARK-22050] give a way to log BlockUpdated events. Actually, the ExecutorMetricsUpdates are also very useful if it can be persisted for further analysis. 

As a performance reason and actual use case, the PR offers a fraction configuration which can sample the events to be persisted. we also refactor for BlockUpdated with the same sampling way.
