# EMR Notebooks 的示例编程命令
## 概述
您可以通过脚本或命令行执行 APIs 来执行 EMR 笔记本。当您在 AWS 控制台之外启动、停止、列出和描述 EMR 笔记本执行时，您可以通过编程方式控制 EMR 笔记本。您可以将不同的参数值传递给带参数化 Notebook 单元格的 Notebook。这样就不必为每组新参数值创建 Notebook 副本。有关更多信息，请参阅 [Amazon EMR API actions](https://docs.aws.amazon.com/emr/latest/APIReference/API_Operations.html)。
您可以通过Amazon CloudWatch 事件安排或批量执行EMR笔记本和. AWS Lambda有关更多信息，请参阅[AWS Lambda 与 Amazon CloudWatch 活动配合使用](https://docs.aws.amazon.com/lambda/latest/dg/services-cloudwatchevents.html)。
**注意**
EMR Notebooks 在控制台中作为 Amazon EMR Studio Workspaces 提供。通过控制台中的**创建 Workspace** 按钮，可以创建新的 Notebooks。要访问或创建 Workspaces，EMR Notebooks 用户需要额外的 IAM 角色权限。有关更多信息，请参阅 [Amazon EMR Notebooks 是控制台中的 Amazon EMR Studio Workspaces](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-managed-notebooks-migration.html) 和 [Amazon EMR 控制台](https://docs.aws.amazon.com/emr/latest/ManagementGuide/whats-new-in-console.html)。
## 编程执行的角色权限
要在 EMR Notebooks 中使用编程执行，您必须使用以下策略配置用户权限：
------
#### [ JSON ]
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Sid": "AllowExecutionActions",
"Effect": "Allow",
"Action": [
"elasticmapreduce:StartNotebookExecution",
"elasticmapreduce:DescribeNotebookExecution",
"elasticmapreduce:ListNotebookExecutions"
],
"Resource": [
"*"
]
},
{
"Sid": "AllowPassingServiceRole",
"Effect": "Allow",
"Action": [
"iam:PassRole"
],
"Resource": [
"arn:aws:iam::123456789012:role/EMR_Notebooks_DefaultRole"
]
}
]
}
```
------
在 EMR Notebooks 集群上以编程方式执行 EMR Notebooks 时，您必须添加以下额外权限：
------
#### [ JSON ]
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Sid": "AllowRetrievingManagedEndpointCredentials",
"Effect": "Allow",
"Action": [
"emr-containers:GetManagedEndpointSessionCredentials"
],
"Resource": [
"arn:aws:emr-containers:*:123456789012:/virtualclusters/virtual-cluster-id/endpoints/managed-endpoint-id"
],
"Condition": {
"StringEquals": {
"emr-containers:ExecutionRoleArn": [
"arn:aws:iam::123456789012:role/emr-on-eks-execution-role"
]
}
}
},
{
"Sid": "AllowDescribingManagedEndpoint",
"Effect": "Allow",
"Action": [
"emr-containers:DescribeManagedEndpoint"
],
"Resource": [
"arn:aws:emr-containers:*:123456789012:/virtualclusters/virtual-cluster-id/endpoints/managed-endpoint-id"
]
}
]
}
```
------
## 编程执行的限制
+ 每个 AWS 区域 账户最多支持 100 个并发执行。
+ 如果运行超过 30 天，则会终止执行。
+ Amazon EMR Serverless 交互式应用程序不支持以编程方式执行 Notebooks 电脑实例。
## 编程 EMR Notebook 执行示例
以下各节提供了使用 AWS CLI、Boto3 SDK (Python) 和 Ruby 以编程方式执行 EMR 笔记本的几个示例：
+ [EMR Studio 中的 Notebook CLI 命令示例](emr-managed-notebooks-headless-cli.md)
+ [EMR Notebook 的 Python 示例](emr-managed-notebooks-headless-python.md)
+ [EMR Notebook 的 Ruby 示例](emr-managed-notebooks-headless-ruby.md)
您还可以使用编排工具 [例如 Apache Airflow 或 Amazon Managed Workflows for Apache Airflow（MWAA）]，将参数化 Notebooks 作为计划工作流的一部分运行。有关更多信息，请参阅AWS 大数据博客中的 [Orchestrating analytics jobs on EMR Notebooks using MWAA](https://aws.amazon.com/blogs/big-data/orchestrating-analytics-jobs-on-amazon-emr-notebooks-using-amazon-mwaa/)。**
# EMR Studio 中的 Notebook CLI 命令示例
本主题显示了 EMR Notebook 的 CLI 命令示例。该示例使用 EMR Notebooks 控制台中的演示 Notebook。要查找 Notebook，请使用相对于主目录的文件路径。在此示例中，您可以运行两个 Notebook 文件：`demo_pyspark.ipynb` 和 `my_folder/python3.ipynb`。
**注意**
EMR Notebooks 在控制台中作为 Amazon EMR Studio Workspaces 提供。通过控制台中的**创建 Workspace** 按钮，可以创建新的 Notebooks。要访问或创建 Workspaces，EMR Notebooks 用户需要额外的 IAM 角色权限。有关更多信息，请参阅 [Amazon EMR Notebooks 是控制台中的 Amazon EMR Studio Workspaces](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-managed-notebooks-migration.html) 和 [Amazon EMR 控制台](https://docs.aws.amazon.com/emr/latest/ManagementGuide/whats-new-in-console.html)。
文件 `demo_pyspark.ipynb` 的相对路径是 `demo_pyspark.ipynb`，如下所示。
![\[Jupyter notebook interface showing a file explorer and code editor with PySpark content.\]](http://docs.aws.amazon.com/zh_cn/emr/latest/ManagementGuide/images/notebook_exe_folder_structure_1.png)
`python3.ipynb` 的相对路径是 `my_folder/python3.ipynb`，如下所示。

有关 Amazon EMR API `NotebookExecution` 操作的更多信息，请参阅 [Amazon EMR API actions](https://docs.aws.amazon.com/emr/latest/APIReference/API_Operations.html)。
## 运行 Notebook
您可以使用 AWS CLI 来运行带有`start-notebook-execution`操作的笔记本，如以下示例所示。
**Example ：使用（运行在 Amazon EC2 上的）Amazon EMR 集群在 EMR Studio Workspace 中执行 EMR Notebook。**
```
aws emr --region us-east-1 \
start-notebook-execution \
--editor-id e-ABCDEFG123456 \
--notebook-params '{"input_param":"my-value", "good_superhero":["superman", "batman"]}' \
--relative-path test.ipynb \
--notebook-execution-name my-execution \
--execution-engine '{"Id" : "j-1234ABCD123"}' \
--service-role EMR_Notebooks_DefaultRole
{
"NotebookExecutionId": "ex-ABCDEFGHIJ1234ABCD"
}
```
**Example ：使用 EMR Notebooks 集群在 EMR Studio Workspace 中执行 EMR Notebook。**
```
aws emr start-notebook-execution \
--region us-east-1 \
--service-role EMR_Notebooks_DefaultRole \
--environment-variables '{"KERNEL_EXTRA_SPARK_OPTS": "--conf spark.executor.instances=1", "KERNEL_LAUNCH_TIMEOUT": "350"}' \
--output-notebook-format HTML \
--execution-engine Id=arn:aws:emr-containers:us-west-2:account-id:/virtualclusters/ABCDEFG/endpoints/ABCDEF,Type=EMR_ON_EKS,ExecutionRoleArn=arn:aws:iam::account-id:role/execution-role \
--editor-id e-ABCDEFG \
--relative-path EMRonEKS-spark_python.ipynb
```
**Example ：执行 EMR Notebook 来指定其 Amazon S3 位置**
```
aws emr start-notebook-execution \
--region us-east-1 \
--notebook-execution-name my-execution-on-emr-on-eks-cluster \
--service-role EMR_Notebooks_DefaultRole \
--environment-variables '{"KERNEL_EXTRA_SPARK_OPTS": "--conf spark.executor.instances=1", "KERNEL_LAUNCH_TIMEOUT": "350"}' \
--output-notebook-format HTML \
--execution-engine Id=arn:aws:emr-containers:us-west-2:account-id:/virtualclusters/ABCDEF/endpoints/ABCDEF,Type=EMR_ON_EKS,ExecutionRoleArn=arn:aws:iam::account-id:role/execution-role \
--notebook-s3-location '{"Bucket": "amzn-s3-demo-bucket","Key": "s3-prefix-to-notebook-location/EMRonEKS-spark_python.ipynb"}' \
--output-notebook-s3-location '{"Bucket": "amzn-s3-demo-bucket","Key": "s3-prefix-for-storing-output-notebook"}'
```
## Notebook 输出

## 描述 Notebook
您可以使用 `describe-notebook-execution` 操作以访问关于特定 Notebook 执行的信息。
```
aws emr --region us-east-1 \
describe-notebook-execution --notebook-execution-id ex-IZWZZVR9DKQ9WQ7VZWXJZR29UGHTE
{
"NotebookExecution": {
"NotebookExecutionId": "ex-IZWZZVR9DKQ9WQ7VZWXJZR29UGHTE",
"EditorId": "e-BKTM2DIHXBEDRU44ANWRKIU8N",
"ExecutionEngine": {
"Id": "j-2QMOV6JAX1TS2",
"Type": "EMR",
"MasterInstanceSecurityGroupId": "sg-05ce12e58cd4f715e"
},
"NotebookExecutionName": "my-execution",
"NotebookParams": "{\"input_param\":\"my-value\", \"good_superhero\":[\"superman\", \"batman\"]}",
"Status": "FINISHED",

}
```
## 停止运行 Notebook
如果您想要停止 Notebook 正在运行的执行，您可以借助 `stop-notebook-execution` 命令。
```
# stop a running execution
aws emr --region us-east-1 \
stop-notebook-execution --notebook-execution-id ex-IZWZX78UVPAATC8LHJR129B1RBN4T
# describe it
aws emr --region us-east-1 \
describe-notebook-execution --notebook-execution-id ex-IZWZX78UVPAATC8LHJR129B1RBN4T
{
"NotebookExecution": {
"NotebookExecutionId": "ex-IZWZX78UVPAATC8LHJR129B1RBN4T",
"EditorId": "e-BKTM2DIHXBEDRU44ANWRKIU8N",
"ExecutionEngine": {
"Id": "j-2QMOV6JAX1TS2",
"Type": "EMR"
},

# EMR Notebook 的 Ruby 示例
本主题包含一个演示 Notebook 功能的 Ruby 示例。
**注意**
EMR Notebooks 在控制台中作为 Amazon EMR Studio Workspaces 提供。通过控制台中的**创建 Workspace** 按钮，可以创建新的 Notebooks。要访问或创建 Workspaces，EMR Notebooks 用户需要额外的 IAM 角色权限。有关更多信息，请参阅 [Amazon EMR Notebooks 是控制台中的 Amazon EMR Studio Workspaces](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-managed-notebooks-migration.html) 和 [Amazon EMR 控制台](https://docs.aws.amazon.com/emr/latest/ManagementGuide/whats-new-in-console.html)。
以下 Ruby 代码示例演示了如何使用 Notebook 执行 API。
```
# prepare an Amazon EMR client
emr = Aws::EMR::Client.new(
region: 'us-east-1',
access_key_id: 'AKIA...JKPKA',
secret_access_key: 'rLMeu...vU0OLrAC1',
)
```
## 启动 Notebook 执行并获取执行 ID
在此示例中，Amazon S3 编辑器和 EMR Notebook 是 `s3://amzn-s3-demo-bucket/notebooks/e-EA8VGAA429FEQTC8HC9ZHWISK/test.ipynb`。
有关 Amazon EMR API `NotebookExecution` 操作的更多信息，请参阅 [Amazon EMR API actions](https://docs.aws.amazon.com/emr/latest/APIReference/API_Operations.html)。
```
start_response = emr.start_notebook_execution({
editor_id: "e-EA8VGAA429FEQTC8HC9ZHWISK",
relative_path: "test.ipynb",
execution_engine: {id: "j-3U82I95AMALGE"},
service_role: "EMR_Notebooks_DefaultRole",
})
notebook_execution_id = start_resp.notebook_execution_id
```
## 描述 Notebook 执行并打印详细信息
```
describe_resp = emr.describe_notebook_execution({
notebook_execution_id: notebook_execution_id
})
puts describe_resp.notebook_execution
```
上述命令的输出如下。
```
{
