limit requests from node API clients, so that each Node can only get / list / watch its own Node API object, and can also only get / list / watch Pod API objects bound to that node. Clients using kubelet credentials to read other nodes or unrelated pods must change their authentication credentials (recommended), adjust their usage, or obtain broader read access independent of the node authorizer.

 *  **OkHttp now supports TLS 1.3.** This requires either Conscrypt or Java 11+.

 *  **Proxy authenticators are now asked for preemptive authentication.** OkHttp will now request
    authentication credentials before creating TLS tunnels through HTTP proxies (HTTP `CONNECT`).
    Authenticators should identify preemptive authentications by the presence of a challenge whose
    scheme is "OkHttp-Preemptive".

## **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_**]
