The following ``get-data-lake-settings`` example retrieves the list of data lake administrators and other data lake settings. ::

    aws lakeformation get-data-lake-settings \
        --cli-input-json file://input.json

Contents of ``input.json``::

    {   
        "CatalogId": "123456789111"
    }

Output::

    {
        "DataLakeSettings": {
            "DataLakeAdmins": [{
                "DataLakePrincipalIdentifier": "arn:aws:iam::123456789111:user/lf-admin"
            }],
            "CreateDatabaseDefaultPermissions": [],
            "CreateTableDefaultPermissions": [
                    {

                            },
                            "Permissions": [
