In metrics version 3, all metrics are available under the endpoint:

```
/minio/metrics/v3
```

however, a specific path under this is required.

Metrics are organized into groups at paths **relative** to the top-level endpoint above.

## Metrics Request Handling

Each endpoint below can be queried at different intervals as needed via a scrape configuration in Prometheus or a compatible metrics collection tool.

	// save top-level help for deprecated sub-systems in a separate map.
	deprecatedHelpKVMap := map[string]config.HelpKV{
		config.RegionSubSys: {
			Key:         config.RegionSubSys,

Kubernetes manages stateless Spark and Hive containers elastically on the compute nodes. Spark has native scheduler integration with Kubernetes. Hive, for legacy reasons, uses YARN scheduler on top of Kubernetes.
