Apache Spark reassigned SPARK-8694:
-----------------------------------
Assignee: Apache Spark
> Defer executing drawTaskAssignmentTimeline until page loaded to avoid to
> freeze the page
> ----------------------------------------------------------------------------------------
>
> Key: SPARK-8694
> URL: https://issues.apache.org/jira/browse/SPARK-8694
> Project: Spark
> Issue Type: Sub-task
> Components: Web UI
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Kousuke Saruta
> Assignee: Apache Spark
>
> When there are massive tasks in the stage page (such as, running
> sc.parallelize(1 to 100000, 10000).count()), Event Timeline needs 15+ seconds
> to render the graph (drawTaskAssignmentTimeline) in my environment. The page
> is unresponsive until the graph is ready.
> However, since Event Timeline is hidden by default, we can defer
> drawTaskAssignmentTimeline until page loaded to avoid freezing the page. So
> that the user can view the page while rendering Event Timeline in the
> background.
> This PR puts drawTaskAssignmentTimeline into $(function(){}) to avoid
> blocking loading page.
