This topic provides answers to some frequently asked questions about the preparations that are required for using MaxCompute.
Create a MaxCompute project
Create a RAM user
Prepare an environment and install the required tools
What are the differences between DataWorks and MaxCompute?
MaxCompute is a data warehouse that is used to store data or perform data development and computations.
DataWorks provides features, such as visualized development and node process management, for you to use in MaxCompute. DataWorks works with MaxCompute to provide an end-to-end data processing solution, including data development and data governance. For more information about DataWorks, see What is DataWorks?
How do I distinguish between a DataWorks workspace and a MaxCompute project?
You must create a DataWorks workspace before you create a MaxCompute project. For more information about how to create a MaxCompute project, see Create a MaxCompute project. DataWorks workspaces are distinguished from MaxCompute projects in the following ways:
DataWorks workspaces: Log on to the DataWorks console. In the left-side navigation pane, click Workspaces. On the Workspaces page, you can view the names of the DataWorks workspaces.
MaxCompute project: Log on to the MaxCompute console. In the top navigation bar, select a region. In the left-side navigation pane, choose Workspace > Projects to view the name of the MaxCompute project.
What do I do if the error ODPS-0410051 occurs when I create a MaxCompute project?
The error ODPS-0410051 occurs because the AccessKey pair is invalid. You can go to the AccessKey Pair page in the Resource Access Management (RAM) console to obtain a valid AccessKey pair or create an AccessKey pair.
What do I do if a RAM user cannot be used to access a MaxCompute project?
The RAM user is not authorized to access the MaxCompute project. You must grant the RAM user the required permissions by using the Alibaba Cloud account to which the RAM user belongs. For more information, see Prepare a RAM user.
What do I do if the error ODPS-0410031 occurs when I use the MaxCompute client to access a MaxCompute project?
When the MaxCompute client is started, the following error message appears:
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:2015-12-23T02:16:00.000Z
The local time of the device on which the MaxCompute client is installed is not the same as the time of the MaxCompute server. If the time difference exceeds 15 minutes, the connection request is considered timed out and rejected by the server.
Adjust the local time of the device on which the MaxCompute client is installed. Then, restart the MaxCompute client.
What are the platforms that MaxCompute Studio can be integrated with?
MaxCompute Studio is a big data integrated development environment (IDE) tool that is provided by Alibaba Cloud MaxCompute. MaxCompute Studio can be integrated with IntelliJ IDEA and PyCharm. For more information about how to configure MaxCompute Studio, see Configure MaxCompute Studio.
