## **3. Configure Hadoop, Spark, Hive to use MinIO**

After successful installation navigate to the Ambari UI `http://<ambari-server>:8080/` and login using the default credentials: [**_username: admin, password: admin_**]

- MinIO exports Prometheus compatible data by default which is bucket centric as an authorized endpoint at `/minio/v2/metrics/bucket`.

This document explains how to setup Prometheus and configure it to scrape data from MinIO servers.

## Prerequisites

To get started with MinIO, refer [MinIO QuickStart Document](https://min.io/docs/minio/linux/index.html#quickstart-for-linux).

For a standard Kubernetes deployment, both CA and discovery will use JWT authentication, with a token automatically
[generated and rotated by Kubernetes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#service-account-token-volume-projection).

For discovery, the JWT token will be read directly from a file and sent as is. For CA, this logic is a bit more complex,
