-----------------------------------------
Hi [~joshrosen], is this still a problem? And if so, do you have a somewhat
_"reliable"_ repro scenario or a nifty way to fake this: {quote}"...(job) lost
some partitions of that stage and had to run a new stage attempt to recompute
one or two tasks from that stage..."{quote}
> Web UI should display separate information for all stage attempts

> Key: SPARK-4836
> URL: https://issues.apache.org/jira/browse/SPARK-4836
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.1.1, 1.2.0
> Reporter: Josh Rosen
>
> I've run into some cases where the web UI job page will say that a job took
> 12 minutes but the sum of that job's stage times is something like 10
> seconds. In this case, it turns out that my job ran a stage to completion
> (which took, say, 5 minutes) then lost some partitions of that stage and had
> to run a new stage attempt to recompute one or two tasks from that stage. As
> a result, the latest attempt for that stage reports only one or two tasks.
> In the web UI, it seems that we only show the latest stage attempt, not all
> attempts, which can lead to confusing / misleading displays for jobs with
> failed / partially-recomputed stages.
