![]() We propose a new Remote Shuffle Service, codenamed RSS, which will move the shuffle from local to remote machines. We will focus on Spark shuffle scalability challenges in this blog post. As outlined in our Spark + AI Summit 2020 talk, currently, shuffle is being done locally in each machine, which poses reliability and stability issues, and other challenges such as hardware stability, compute resource management, and user productivity. A Spark job consists of multiple stages in the current architecture, and shuffle is a well-known methodology to transfer the data between two stages. The optional companion HTML file can be created in the same directory as the XML file or in a different directory.Although Apache Spark has many benefits that contribute to its popularity at Uber and in the industry, we’ve still experienced several challenges in operating Spark at our scale. Optionally, it can save the XML file locally on the machine where it is run. ![]() In both cases, when you "publish" an update to the RSS feed, ListGarden connects to the final web server system to upload an updated copy of the XML file that makes up the RSS feed. In both cases, ListGarden stores information about the RSS feed in a file on the same machine so that it can always continue from where you left off. (ListGarden can communicate locally through HTML and HTTP which is understood by the browser - it does not need a web server on your computer.) When run remotely, the browser connects over the Internet to a normal web server which then executes ListGarden as a normal CGI program. When run locally, the browser connects to the ListGarden program running on the same machine. In both cases the operation of the product is accomplished through a normal web browser. ListGarden can be run in one of two general methods: Local or Remote. The single executable file for Microsoft Windows systems includes the Perl environment built-in, and runs on most normal Windows machines without any additional software. It can run directly on many Mac OS X, Linux, and other Unix-style systems, as well as on many web servers that have the Perl environment installed. ListGarden is written in the Perl computer language. You can also control it from an icon in the system tray. Clicking the "Quit" button on the screen exits the program. This also shows how to customize the companion HTML file output.įor Microsoft Windows systems, ListGarden is available as a single executable file that can automatically launch a browser to control it when run.

The RSS XML and HTML files can be uploaded to any web storage. It also has basic list-maintenance functions making it useful as a simple list manager. ListGarden can produce an optional companion HTML file for human browsers to read. ![]() (Automatic systems with built-in RSS capability include most weblog authoring tools and some content management systems.) The program requires no knowledge of XML or the RSS data format, and is tuned for quick additions of new items and simple editing. It can be used for RSS feeds that are change logs, event lists, lists of physical objects, or post lists of podcasts and manually authored weblogs. It is useful for RSS feeds that need to be maintained without an automatic system that has built-in RSS generation capability. The resulting XML file may be stored locally or automatically copied to a remote web server using FTP. (To learn what an RSS feed is, read " What is RSS?".)
