| There are some functionality which couldn’t be accessed without using ozone sh commands. For example: |
| Creating volumes with quota Managing internal ACLs Creating buckets with encryption key All of these are one-time, administration tasks. Applications can use Ozone without this CLI using other interface like Hadoop Compatible File System (o3fs or ofs) or S3 interface.</p> |
