    E-MapReduce:Announcement on the migration of data from EMR Data Platform in the old EMR console

    Last Updated:Aug 24, 2023

    E-MapReduce (EMR) Data Platform entered the maintenance state at 21:00 on February 21, 2022 (UTC+8). The data development features in Data Platform are no longer updated. If you still use Data Platform to develop data, migrate data from Data Platform to EMR Workflow at the earliest opportunity for data development. This topic describes how to migrate data from Data Platform to EMR Workflow.

    E-MapReduce (EMR) Workflow is a fully managed service that can be used to schedule workflows and tasks. This service is fully compatible with open source Apache DolphinScheduler. EMR Workflow provides easy-to-use scheduling services. You can manage workflows and tasks with ease based on a visualized operation interface and efficiently build data warehouses. This ensures that production tasks can be run stably.

    For more information about EMR Workflow, see What is EMR Workflow?

    If you want to migrate data from Data Platform to DataWorks, see End of updates for data development features in EMR Data Platform.

    Migration process

    You can use EMR Workflow to export workflows and tasks in Data Platform in the old EMR console as a JSON file that is compatible with open source Apache DolphinScheduler. Then, you can use the import feature of EMR Workflow to import the workflows and tasks to implement efficient data migration. This helps reduce migration costs.

    2. Migration

    1. Export workflows and tasks in Data Platform in the old EMR console as a JSON file that describes workflows.

    2. Import the JSON file to EMR Workflow.

    Note

    The export and import operations in the migration phase do not affect the scheduling of tasks in Data Platform in the old EMR console.

    3. Check

    By default, workflows that are imported to EMR Workflow are in the offline state. You must manually run workflows one at a time or perform time-based scheduling on the workflows to observe the running results of the workflows.

    Note

    If you have questions during the running process, you can contact the Alibaba Cloud EMR team. Engineers in the team will locate and analyze issues and provide a solution.
