Koordinator YARN Copilot

English | 简体中文

Introduction

Koordinator has supported hybrid orchestration workloads on Kubernetes, so that batch jobs can use the requested but unused resource as koord-batch priority and BE QoS class to improve the cluster utilization. However, there are still lots of applications running beyond K8s such as Apache Haddop YARN. As a resource management platform in BigData ecosystem, YARN has supported numbers of computing engines including MapReduce, Spark, Flink, Presto, etc.

In order to extend the co-location scenario of Koordinator, now the community has provided Hadoop YARN extended suits Koordinator YARN Copilot in BigData ecosystem, supporting running Hadoop YARN jobs by koord-batch resources with other K8s pods. The Koordinator YARN Copilot has following characteristics:

• Open-Source native: implement against open-sourced version of Hadoop YARN; so there is no hack inside YARN modules.
• Unifed resource priority and QoS strategy: the suits aims to the koord-batch priority of Koordinator, and also managed by QoS strategies of koordlet.
• Resource sharing on node level: node resources of koord-batch priority can be requested by tasks of YARN or Batch pods both.
• Adaptive for multiple environments: the suits can be run under any environment, including public cloud or IDC.

Quick Start

You can view the full documentation from the Koordinator website.

• Install or upgrade Koordinator with the latest version.
• Referring to best practices, there will be detailed instructions for running Hadoop YARN jobs with Koordinator batch resources in K8s.
