Exemplos de Python para um caderno do EMR

Este tópico contém um exemplo de arquivo de comando. O exemplo de código corresponde a um arquivo do SDK para Python (Boto3) chamado demo.py. Ele mostra as APIs de execução do caderno.

nota

Os cadernos do EMR estão disponíveis como Workspaces do EMR Studio no console. O botão Criar Workspace no console permite criar cadernos. Para acessar ou criar Workspaces, os usuários dos Cadernos do EMR precisam de permissões adicionais de perfil do IAM. Para obter mais informações, consulte Amazon EMR Notebooks are Amazon EMR Studio Workspaces in the console e console do Amazon EMR.

Para obter informações sobre as ações da API NotebookExecution do Amazon EMR, consulte Amazon EMR API actions.
