Kousuke Saruta created SPARK-3468:
-------------------------------------

             Summary: WebUI Timeline-View feature
                 Key: SPARK-3468
                 URL: https://issues.apache.org/jira/browse/SPARK-3468
             Project: Spark
          Issue Type: New Feature
          Components: Web UI
            Reporter: Kousuke Saruta


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.
