> Current Stage page's task table will throw an exception when there's no complete tasks,
to reproduce this issue, user could submit code like:
> {code}
> sc.parallelize(1 to 20, 20).map { i => Thread.sleep(10000); i }.collect()
> {code}
> Then open the UI and click into stage details. Below is the screenshot.

> Deep dive into the code, found that current UI can only show the completed tasks, it
is different from 2.2 code.
