----------------------------------
Comment: was deleted
(was: Sorry for pending this ticket for a long time. I've re considered how and
what to visualize.
One of my ideas, "Timeline based visualization" for each task at a stage, is
taking a shape and almost be implemented.

This feature is integrated into existing WebUI, zoomable and scrollable.
Now the code of this feature is a little bit messy but I'll cleanup and show
the code soon.)

> Key: SPARK-3468
> URL: https://issues.apache.org/jira/browse/SPARK-3468
> Project: Spark
> Issue Type: New Feature
> Components: Web UI
> Affects Versions: 1.4.0
> Reporter: Kousuke Saruta
> Attachments: tasks.png

> I sometimes trouble-shoot and analyse the cause of long time spending job.
> At the time, I find the stages which spends long time or fails, then I find
> the tasks which spends long time or fails, next I analyse the proportion of
> each phase in a task.
> Another case, I find executors which spends long time for running a task and
> analyse the details of a task.
> In such situation, I think it's helpful to visualize timeline view of stages
> / tasks / executors and visualize details of proportion of activity for each
> task.
> Now I'm developing prototypes like captures I attached.
> I'll integrate these viewer into WebUI.
