PROJECT SLIDER

##Introduction

SLIDER: A collection of tools and technologies to simplify the packaging, deployment and management of long-running applications on YARN.

• Availability (always-on) - YARN works with the application to ensure recovery or restart of running application components.
• Flexibility (dynamic scaling) - YARN provides the application with the facilities to allow for scale-up or scale-down
• Resource Mgmt (optimization) - YARN handles allocation of cluster resources.

Terminology

Apps on YARN

• Application written to run directly on YARN
• Packaging, deployment and lifecycle management are custom built for each application

Slider Apps

• Applications deployed and managed on YARN using Slider
• Use of slider minimizes custom code for deployment + lifecycle management
• Requires apps to follow Slider guidelines and packaging (“Sliderize”)
