---------------------------------

             Summary: Succeeded tasks num not equal in job page and job detail 
page on spark web ui when speculative task(s) exist
                 Key: SPARK-20591
                 URL: https://issues.apache.org/jira/browse/SPARK-20591
             Project: Spark
          Issue Type: Improvement
          Components: Web UI
    Affects Versions: 2.0.2
            Reporter: Jinhua Fu


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?
