      Description

      If a user ever tries to view specific stage stats, for example, a repartition stage which involves 30000 partitions, the Web UI attempts to load every single task result onto a single webpage, which is completely destroying CPU usage on the driver, which subsequently causes the remaining tasks / jobs to be nearly impossible to complete.

      Ideally the task results should be paged (if not too much trouble) to prevent this from happening.
