### Installing the Chart (toy-setup)

Minimal toy setup for testing purposes can be deployed using:

```bash
helm install --set resources.requests.memory=512Mi --set replicas=1 --set persistence.enabled=false --set mode=standalone --set rootUser=rootuser,rootPassword=rootpass123 --generate-name minio/minio
```

### Upgrading the Chart

```
./bin/spark-submit --class org.apache.spark.examples.SparkPi \
    --master yarn-client \
    --num-executors 1 \
    --driver-memory 512m \
    --executor-memory 512m \
    --executor-cores 1 \
    examples/jars/spark-examples*.jar 10
```

The job should produce an output as shown below. Note the value of pi in the output.

- Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily.
