Apache Spark reassigned SPARK-14628:
------------------------------------
Assignee: Apache Spark
> Remove all the Options in TaskMetrics
> -------------------------------------
>
> Key: SPARK-14628
> URL: https://issues.apache.org/jira/browse/SPARK-14628
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Reporter: Reynold Xin
> Assignee: Apache Spark
>
> Part of the reason why TaskMetrics and its callers are complicated are due to
> the optional metrics we collect, including input, output, shuffle read, and
> shuffle write. Given their values are zero, I think we can always track them.
> It is usually very obvious whether a task is supposed to read any data or
> not. By always tracking them, we can remove a lot of map, foreach, flatMap,
> getOrElse(0L) calls throughout Spark.
