- Navigate to a node with the Spark client and access the spark2-client directory:

```
cd /usr/hdp/current/spark2-client
su spark
```

- 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 \

要发送的载荷也会有自动补全：

/// tip | 提示

请注意 `name` 和 `price` 的自动补全，它们是在 FastAPI 应用中的 `Item` 模型里定义的。

你发送的数据如果不符合要求，会在编辑器中显示内联错误：
