笔记本执行 Python 示例

注意

EMR Notebooks 在新控制台中作为 Amazon EMR Studio Workspaces 提供。您仍然可以在旧控制台中使用现有笔记本，但无法在其中创建新笔记本。新控制台中的创建 Workspace 按钮将取代此功能。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 are Amazon EMR Studio Workspaces in new console（Amazon EMR Notebooks 在新控制台中为 Amazon EMR Studio Workspaces）和 What's new in the console?（控制台中有哪些新功能？）

以下代码示例是一个名为 demo.py 的 SDK for Python（Boto3）文件，用于显示笔记本执行 API。

有关 Amazon EMR API NotebookExecution 操作的更多信息，请参阅 Amazon EMR API actions。

import boto3,time

emr = boto3.client(
    'emr',
    region_name='us-west-1'
)     
     
start_resp = emr.start_notebook_execution(
    EditorId='e-40AC8ZO6EGGCPJ4DLO48KGGGI',
    RelativePath='boto3_demo.ipynb',
    ExecutionEngine={'Id':'j-1HYZS6JQKV11Q'},
    ServiceRole='EMR_Notebooks_DefaultRole'
)

execution_id = start_resp["NotebookExecutionId"]
print(execution_id)
print("\n")
     
describe_response = emr.describe_notebook_execution(NotebookExecutionId=execution_id)
     
print(describe_response)
print("\n")
     
list_response = emr.list_notebook_executions()
print("Existing notebook executions:\n")
for execution in list_response['NotebookExecutions']:
    print(execution)
    print("\n")  
     
print("Sleeping for 5 sec...")
time.sleep(5)
     
print("Stop execution " + execution_id)
emr.stop_notebook_execution(NotebookExecutionId=execution_id)
describe_response = emr.describe_notebook_execution(NotebookExecutionId=execution_id)
print(describe_response)
print("\n")

下面是运行 demo.py 的输出。
