Description

Visualizing how tasks in a stage spend their time can be very helpful to understanding performance. Many folks have started using the visualization tools here: https://github.com/kayousterhout/trace-analysis (see the README at the bottom) to analyze their jobs after they've finished running, but it would be great if this functionality were natively integrated into Spark's UI.

I'd propose adding a relatively simple visualization to the stage detail page, that's hidden by default but that users can view by clicking on a drop-down menu. The plan is to implement this using D3; a mock up of how this would look (that uses D3) is attached. One change we'll make for the initial implementation, compared to the attached visualization, is tasks will be sorted by start time.

This is intended to be a much simpler and more limited version of SPARK-3468
