```

Let's take for example a set of 12 compute nodes with an aggregate memory of _1.2TiB_, we need to do following settings for optimal results. Add the following optimal entries for _core-site.xml_ to configure _s3a_ with **MinIO**. Most important options here are

```
cat ${HADOOP_CONF_DIR}/core-site.xml | kv-pairify | grep "mapred"

> NOTE: Dex supports groups with external connectors so you can use `groups` as policy claim instead of `name`.

```
export MINIO_IDENTITY_OPENID_CLAIM_NAME=groups
```

and add relevant policies on MinIO using `mc admin policy create myminio/ <group_name> group-access.json`
