Apache YuniKorn - A Universal Scheduler

Build Status codecov Go Report Card License Repo Size

Apache YuniKorn is a light-weight, universal resource scheduler for container orchestrator systems. It is created to achieve fine-grained resource sharing for various workloads efficiently on a large scale, multi-tenant, and cloud-native environment. YuniKorn brings a unified, cross-platform, scheduling experience for mixed workloads that consist of stateless batch workloads and stateful services.

YuniKorn now supports K8s and can be deployed as a custom K8s scheduler. YuniKorn's architecture design also allows adding different shim layer and adopt to different ResourceManager implementation including Apache Hadoop YARN, or any other systems.

Get Started

Code Structure

Apache YuniKorn project has the following git repositories:

The yunikorn-core is the brain of the scheduler, which makes placement decisions (allocate container X on node Y) according to the builtin rich scheduling policies. Scheduler core implementation is agnostic to the underneath resource manager system.
