Why have not the metric been added? I think this is rather important, for that
it may affect the results of the research work on this :

> Add task metric to report spill time
> ------------------------------------
>
> Key: SPARK-3577
> URL: https://issues.apache.org/jira/browse/SPARK-3577
> Project: Spark
> Issue Type: Bug
> Components: Shuffle, Spark Core
> Affects Versions: 1.1.0
> Reporter: Kay Ousterhout
> Assignee: Sandy Ryza
> Priority: Minor
>
> The {{ExternalSorter}} passes its own {{ShuffleWriteMetrics}} into
> {{ExternalSorter}}. The write time recorded in those metrics is never used.
> We should probably add task metrics to report this spill time, since for
> shuffles, this would have previously been reported as part of shuffle write
> time (with the original hash-based sorter).
