Theodore Vasiloudis commented on SPARK-11384:
---------------------------------------------
If you look at the screenshot and focus on the duration for the task that reads
Cluster:164.
Even though the total job runtime at the time I took the screenshot was ~53min
that particular task has its duration reported as the total runtime until that
time, instead of the actual time it took to run.
That task involves a cached RDD, but I'm not sure if that is relevant.
Is this the intended behavior? Shouldn't each task report the time it took to
run individually?
> Wrong duration times for (cached) iterative tasks

> In the Web UI when I'm running a job that includes an iteration, some stages
> that include an RDD that I cache appear multiple times, and it seems their
> duration is just incremented instead of reset at the beginning of each
> iteration.
> I will try to attach a screenshot to better explain this.
