What are the differences between DataWorks and MaxCompute?
MaxCompute is a data warehouse for storing data and running data development and computation workloads.
DataWorks sits on top of MaxCompute and provides a visual development environment with features like node workflow management. Together, the two services form an end-to-end data processing solution covering data development and data governance. See What is DataWorks?
How do I tell a DataWorks workspace apart from a MaxCompute project?
A DataWorks workspace must exist before you can create a MaxCompute project. They are managed in separate consoles:
-
DataWorks workspace: Log in to the DataWorks console. In the left navigation pane, click Workspace to view your workspaces.
-
MaxCompute project: Log in to the MaxCompute console. Select a region in the top navigation bar, then choose Workspace > Projects to view your projects.
For steps to create a MaxCompute project, see Create a MaxCompute project.
What do I do if error ODPS-0410051 appears when I create a MaxCompute project?
Cause: Your AccessKey pair is invalid.
Solution: Go to the AccessKey Pair page in the Resource Access Management (RAM) console to get a valid AccessKey pair or create a new one.
What do I do if a RAM user can't access a MaxCompute project?
Cause: The RAM user hasn't been granted access to the project.
Solution: Log in with the Alibaba Cloud account that owns the RAM user and grant the required permissions.
Permissions must be granted by the Alibaba Cloud account that owns the RAM user — a RAM user cannot grant its own project access.
For step-by-step instructions, see Prepare a RAM user.
What do I do if error ODPS-0410031 appears when I use the MaxCompute client?
Error:
FAILED: ODPS-0410031:Authentication request expired - the expire time interval exceeds the max limitation: 900000, max_interval_date:900000,expire_date:2015-12-23T10:15:31.000Z,now_date:2015-12-23T02:16:00.000ZCause: The client's local clock is out of sync with the MaxCompute server. If the time difference exceeds 15 minutes, the server rejects the authentication request.
Solution: Sync your device's clock to the correct time, then restart the MaxCompute client.
Which platforms does MaxCompute Studio integrate with?
MaxCompute Studio is a big data integrated development environment (IDE) provided by Alibaba Cloud MaxCompute. It integrates with IntelliJ IDEA and PyCharm. For setup instructions, see Configure MaxCompute Studio.
