Sean Owen updated SPARK-20970:
------------------------------
Target Version/s: 3.0.0
> Deprecate TaskMetrics._updatedBlockStatuses
> -------------------------------------------
>
> Key: SPARK-20970
> URL: https://issues.apache.org/jira/browse/SPARK-20970
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.2.0
> Reporter: Thomas Graves
>
> 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.
