Once the config changes are applied, proceed to restart **Hadoop** services.

### **3.2 Configure Spark2**

Navigate to **Services** -> **Spark2** -> **CONFIGS** as shown below

	exit_1
fi

sleep 10

./mc idp ldap policy entities minio1
./mc idp ldap policy entities minio2
./mc idp ldap policy entities minio3

./mc admin service restart minio1
./mc admin service restart minio2
./mc admin service restart minio3

sleep 10

./mc idp ldap policy entities minio1
./mc idp ldap policy entities minio2
./mc idp ldap policy entities minio3

Here are some possible ideas:

* An "Init Container" in Kubernetes that runs before your app container
* A bash script that runs the previous steps and then starts your application
    * You would still need a way to start/restart *that* bash script, detect errors, etc.

mc admin config get myminio/ logger_webhook
logger_webhook:name1 auth_token="" endpoint=""
```

```
mc admin config set myminio logger_webhook:name1 auth_token="" endpoint="http://endpoint:port/path"
mc admin service restart myminio
```

NOTE: `http://endpoint:port/path` is a placeholder value to indicate the URL format, please change this accordingly as per your configuration.

access to port 9000

```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

```sh
iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart
```

## Test MinIO Connectivity

### Test using MinIO Console

* Bump to container-vm-v20160321 ([#23313](https://github.com/kubernetes/kubernetes/pull/23313), [@zmerlynn](https://github.com/zmerlynn))
* Remove the restart-kube-proxy and restart-apiserver functions ([#23180](https://github.com/kubernetes/kubernetes/pull/23180), [@roberthbailey](https://github.com/roberthbailey))

## Using MinIO Console

To support WebIdentity based login for MinIO Console, set openid configuration and restart MinIO

```
mc admin config set myminio identity_openid config_url="<CONFIG_URL>" client_id="<client_identifier>"
```

```
mc admin service restart myminio
```
