- Run the Apache Spark Pi job in yarn-client mode, using code from **org.apache.spark**:

```
./bin/spark-submit --class org.apache.spark.examples.SparkPi \
    --master yarn-client \
    --num-executors 1 \
    --driver-memory 512m \
    --executor-memory 512m \
    --executor-cores 1 \
    examples/jars/spark-examples*.jar 10
```

The job should produce an output as shown below. Note the value of pi in the output.

```

虽然表单字段的名称是 `scope`（单数），但实际上，它是以空格分隔的，由多个**scope**组成的长字符串。

**作用域**只是不带空格的字符串。

常用于声明指定安全权限，例如：

* 常见用例为，`users:read` 或 `users:write`
* 脸书和 Instagram 使用 `instagram_basic`
* 谷歌使用 `https://www.googleapis.com/auth/drive`

!!! info "说明"

    OAuth2 中，**作用域**只是声明指定权限的字符串。

    是否使用冒号 `:` 等符号，或是不是 URL 并不重要。

    这些细节只是特定的实现方式。

    对 OAuth2 来说，都只是字符串而已。

## 获取 `username` 和 `password` 的代码

  // that will be used by the driver when allocating a resource for the
