You can create and run multiple 'replication' jobs at a time there are no predefined limits set.

## Batch Jobs Terminology

### Job
A job is the basic unit of work for MinIO Batch Job. A job is a self describing YAML, once this YAML is submitted and evaluated - MinIO performs the requested actions on each of the objects obtained under the described criteria in job YAML file.

### Type

import okhttp3.internal.http.parseChallenges
import okio.Buffer
import okio.Socket

/**
 * An HTTP response. Instances of this class are not immutable: the response body is a one-shot
 * value that may be consumed only once and then closed. All other properties are immutable.
 *
 * This class implements [Closeable]. Closing it simply closes its response body. See
 * [ResponseBody] for an explanation and examples.

```
mc admin policy attach myminio userManager adminManageUser.json
```

Create a new admin user `admin1` on MinIO use `mc admin user`.

```
mc admin user add myminio admin1 admin123
```

Once the user is successfully created you can now apply the `userManage` policy for this user.

```
mc admin policy attach myminio userManager --user=admin1
```

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