[jira] [Commented] (SPARK-2115) Stage kill link is too close to
stage details link
[ https://issues.apache.org/jira/browse/SPARK-2115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14489229#comment-14489229 ]
Dev Lakhani commented on SPARK-2115:
------------------------------------
On a similar note: When the kill link is cached in the browser bar, it's easy to accidentally kill a job just by pressing enter. For example:
You press the kill stage button and get the prompt whether you want to kill the stage. You launch a new job and start typing:
http://localhost:4040/
Chrome for example starts auto completing with http://localhost:4040/stages/kill/?id=0&terminate=true , if you accidentally press enter it will kill the current stage without any prompts.
I think its also a bit of a security issue if from any host you can curl/wget/issue: http://localhost:4040/stages/kill/?id=0&terminate=true and it will kill the current stage without prompting.

> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 1.0.0
> Reporter: Nicholas Chammas
> Assignee: Masayoshi TSUZUKI
> Priority: Trivial
> Fix For: 1.1.0

> 1.0.0 introduces a new and very helpful `kill` link for each active stage in the Web UI.
> The problem is that this link is awfully close to the link one would click on to see details for the stage. Without any confirmation dialog for the kill, I think it is likely that users will accidentally kill stages when all they really wanted was to see more information about them.
> I suggest moving the kill link to the right of the stage detail link, and having it flush right within the cell. This puts a safe amount of space between the two links while keeping the kill link in a consistent location.
