Hi Jiwon, Slider supports horizontally scale out/in your application. Please refer to following link for the user doc of slider commands which describes "slider flex ..."
http://slider.incubator.apache.org/docs/manpage.html Besides, YARN 1197 plans to support resizing YARN container. By leveraging it, Slider is able to support vertically scale up/down your application instance, for example increasing memory from 2GB to 4GB. https://issues.apache.org/jira/browse/YARN-1197 Based on slider's capabilities of scale out/in and scale up/down, you could develop a driver to automatically flex your application. As I know there is a team who is working on an open source general auto-scaler for YARN/Slider based application which is named as Jaguar. You may contact them for details. https://hadoopsummit.uservoice.com/forums/283262-hadoop-governance-security-operations/suggestions/7074316-project-jaguar-an-application-autoscaler-for-hado Please feel free to let me know if you have any question.
