Yes, right now the landing page of the UI is the stage page, which is a
little arbitrary. I think it makes sense to have an overview page, that
displays the number of running executors, master URL, total duration, event log
location. (@tdas and I discussed this a bunch in designing for a brother UI for
Spark Streaming.)
On this overview page, maybe we can also add a Job summary table, in which
each row links to a job-specific stages page (what we already have). Then, in
the context of canceling jobs, we can have the `cancel` button at the end of
each Job row.
