> when spark.speculation is enabled,and there are some speculative tasks, then we can see succeeded tasks num include speculative tasks on the job page, which however not being included on the job detail page(job stages page).
> When I consider some tasks may run a little slow by the job page's  succeeded tasks more than total tasks,which make me want to known which tasks and why,I have to check every stage to find the speculative tasks which is beacause speculative tasks not being included in the stage succeeded task num.
> Can it be improved?
> update two screenshots, succeeded task num is 557 on job page,but 550(by sum) on job detail page(stages),the extra 7 tasks are speculative tasks.
