### Upgrading the Chart

You can use Helm to update MinIO version in a live release. Assuming your release is named as `my-release`, get the values using the command:

```bash
helm get values my-release > old_values.yaml
```

Then change the field `image.tag` in `old_values.yaml` file with MinIO image tag you want to use. Now update the chart using

```bash

client_cert_key  (path)      client cert key for mTLS authentication
comment          (sentence)  optionally add a comment to this setting
```

To get ENV equivalent for each config args use `--env` flag

```
~ mc admin config set play/ etcd --env
KEY:
etcd  federate multiple clusters for IAM and Bucket DNS

Spark/Hadoop workloads which use Hadoop MR Committer v1/v2 algorithm upload objects to a temporary prefix in a bucket. These objects are 'renamed' to a different...

For hosts with ufw enabled (Debian based distros), you can use `ufw` command to allow traffic to specific ports. Use below command to allow access to port 9000

```sh
ufw allow 9000
```

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

```sh
ufw allow 9000:9010/tcp
```

### firewall-cmd

The following example submits WordCount code to the Scala shell. Select an input file for the Spark WordCount example. We can use any text file as input.

- Login as user **‘spark’**.
- When the job runs, the library can now use **MinIO** during intermediate processing.
- Navigate to a node with Spark client and access the spark2-client directory:

```
cd /usr/hdp/current/spark2-client

The replication configuration in use on a bucket can be viewed using the `mc replicate export alias/bucket` command.

To disable replica metadata modification syncing, use `mc replicate edit` with the --replicate flag.

```
mc replicate edit alias/bucket --id xyz.id --replicate "delete,delete-marker"
```
