User Quota Tracking

User & Group resource usage are being tracked at queue level considering its hierarchical structure too for property overriding preference as well. Please see YUNIKORN-984 for details.

Enhanced User & Group handling

User & Group handling mechanism has been enhanced, which in turn opened up various ways to detect the User and its associated group. Please see YUNIKORN-1306 for details.

Support app/task priority aware scheduling

In addition to Fair & FIFO based application sorting policies, Priority based sorting has been designed and implemented in such a way to be compatible with Kubernetes standard priority handling wherever possible. Please see YUNIKORN-1 for details.

Support arbitrary resources in namespace annotation

Support for all resource types in namespace annotations is possible now. Earlier only cpu and memory resource type is allowed. Please see YUNIKORN-1275 for details.

Build YuniKorn against Kubernetes 1.23

This will allow us to maintain support for running on 1.21 and later clusters, while also supporting newer scheduler features. Please see YUNIKORN-1348 for details.

Configuration V2

The configuration system has been overhauled YUNIKORN-1221:

  • REST interface for config update has been removed
  • New config map: yunikorn-defaults managed via helm
  • Existing config map retained.

Please read for details

Revamping e2e testing

Stabilization of various end-to-end tests has been covered as part of YUNIKORN-1491.
