Summary: 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
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.
