+#### Using Apache YuniKorn as Customized Scheduler for Spark on Kubernetes
+
+[Apache YuniKorn](https://yunikorn.apache.org/) is a resource scheduler for Kubernetes that provides advanced batch scheduling
+capabilities, such as job queuing, resource fairness, min/max queue capacity and flexible job ordering policies.
+For available Apache YuniKorn features, please refer to [this doc](https://yunikorn.apache.org/docs/next/get_started/core_features).

Review Comment:
   We cannot use the version number alias `next` here because it will be fragile in the future.
   - We need to use a concrete version `v1.0.0` link instead.
   - However, Apache YuniKorn doesn't provide `1.0.0` yet.
     - https://yunikorn.apache.org/docs/1.0.0/ is broken.
     - The only latest version seems to be https://yunikorn.apache.org/docs/0.12.2/ .
   
   We need Apache YuniKorn community's help here, @yangwwei .
