>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.2.0

> TaskMetrics._updatedBlockStatuses isn't used anywhere internally by spark. It 
> could be used by users though since its exposed by  SparkListenerTaskEnd.  We 
> made it configurable to turn off the tracking of it since it uses a lot of 
> memory in https://issues.apache.org/jira/browse/SPARK-20923.  That config is 
> still true for backwards compatibility. We should turn that to false in next 
> release and deprecate that api altogether.
