Welcome to Two Sigma's Cook Scheduler!
What is Cook?
- Cook is a powerful batch scheduler, specifically designed to provide a great user experience when there are more jobs to run than your cluster has capacity for.
- Cook is able to intelligently preempt jobs to ensure that no user ever needs to wait long to get quick answers, while simultaneously helping you to achieve 90%+ utilization for massive workloads.
- Cook has been battle-hardened to automatically recover after dozens of classes of cluster failures.
- Cook can act as a Spark scheduler, and it comes with a REST API and Java client.
Core concepts is a good place to start to learn more.
Check the changelog for release info.
In this repository, you'll find several subprojects, each of which has its own documentation.

jobclient- This is the Java API for Cook, which uses the REST API under the hood.
