> Display time series view for task metrics in history server
> -----------------------------------------------------------
>
> Key: SPARK-33033
> URL: https://issues.apache.org/jira/browse/SPARK-33033
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 3.1.0
> Reporter: Zhen Li
> Priority: Minor
>
> Event log contains all tasks' metrics data, which are useful for performance
> debugging. By now spark UI only displays final aggregation results, much
> information is hidden by this way. If spark UI could provide time series data
> view, it would be more helpful to performance debugging problems. We would
> like to build application statistics page in history server based on task
> metrics to provide more straight forward insight for spark application.
