Andrew Or resolved SPARK-5106.
------------------------------
Resolution: Won't Fix
> Make Web UI automatically refresh/update displayed data
> -------------------------------------------------------
>
> Key: SPARK-5106
> URL: https://issues.apache.org/jira/browse/SPARK-5106
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 1.2.0
> Reporter: Ryan Williams
>
> My (and presumably others') experience monitoring Spark jobs currently
> consists of repeatedly ⌘R'ing various pages of the web UI to view
> ever-fresher data about how many tasks have succeeded / failed, how much
> spillage is happening, etc., which is tedious.
> Particularly unfortunate is the "one refresh over the line" problem where,
> just as things are getting interesting, the job itself fails or finishes, and
> after refreshing the page all data disappears.
> It would be good if the web UI updated the data it was displaying
> automatically.
> One hacky way to achieve this would be to have it automatically refresh the
> page, though this still risks losing everything when the job finishes.
> A better long-term solution would be to have the UI poll for (or have pushed
> to it) updates to the data it is displaying.
> Either way, some way to toggle this functionality on or off is probably
> warranted as well.
