> Add a new button on the thread dump page of Spark Web Ui to download the
> thread dump in text format.
> Right now if a user wants to collect a thread dump for an executor or driver
> using Spark UI, the thread dump is displayed as an html page. User can click
> on expand all button and then save that html file or take screen shots.
> However for debugging purpose it is always helpful to have the jstack output
> in raw text format without any html formatting and the process of saving the
> file should be simple as one click. In this Jira we propose to add a button
> on the Spark Ui page to be able to directly save or display the thread dump
> output in raw text format without html formatting.
