> {code}
> sc.parallelize(1 to 1000000, 1000000).count()
> {code}
> The above code creates one million tasks to be executed. The stage detail web ui page takes forever to load (if it ever completes).
> There are again a few different alternatives:
> 0. Limit the number of tasks we show.
> 1. Pagination
> 2. By default only show the aggregate metrics and failed tasks, and hide the successful ones.
