YI-MapReduce Manager supports four methods to add new configurations.
Method 1: Create New
Scenario
When there is no need to share configurations with other clusters, and the configuration template does not meet usage requirements, users can add a completely new configuration file for the cluster service.
Procedure
1. Log in to the YI-MapReduce management console.
2. Click on My Cluster and choose a running cluster to enter the cluster information page.
3. Click the YI-MapReduce Manager tab, and then select Go to YI-MapReduce Manager.
4. Upon entering the YI-MapReduce Manager, click Cluster Service on the menu to go to the cluster service list.
5. Choose the specific cluster service. Click on the cluster service name to enter the cluster service details page.
6. Click the Configuration Management tab.
7. Choose the configuration group for adding new configurations. Hover over the configuration group name, and click on the Add Configuration icon on the right. The right side of the page will show the new configurations. As shown in the figure:
8. Select Create New as the method for adding, enter the configuration name, and configuration file path, choose the file format, and input the configuration content or add configuration items.
9. Click Save to complete the configuration addition.
Cautions
1. Configuration Name: Only English letters, numbers, and symbols like "_-." are supported. It cannot start with a number.
2. File Path: Only English letters, numbers, and symbols like "_-." are supported. The configuration path must be included in the trustlist.
3. When the file format is text, you need only to input the configuration content. As shown in the figure:
4. For non-text file formats like yaml, xml, or properties, you are required to: select the display level, choose the configuration rule group, and set the configuration items. As shown in the figure:
5. If the display level is set at the configuration item level, the configuration will be displayed as individual configuration items. As shown in the figure:
6. If it is set at the file level, the configuration will be displayed as text. As shown in the figure:
7. Configuration Rule Group: The configuration rule maintained in the system. After selecting the configuration rule group, the configuration items below will display the configuration items included in the configuration rule group. You can edit the configuration values and descriptions of the configuration items brought out by the configuration rule group and continue to add new configuration items.
Method 2: Retrieve Configuration Templates
Scenario
Users may want to use configuration templates directly when adding new configurations to the cluster service.
Procedure
1. Log in to the YI-MapReduce management console.
2. Click on My Cluster and choose a running cluster to enter the cluster information page.
3. Click the YI-MapReduce Manager tab, and then select Go to YI-MapReduce Manager.
4. Upon entering the YI-MapReduce Manager, click Cluster Service on the menu to go to the cluster service list.
5. Choose the specific cluster service. Click on the cluster service name to enter the cluster service details page.

9. Select the configuration name.
10. Click Save to complete the configuration addition.
Method 3: Share Configuration from Other Clusters
Scenario
When the service of the current cluster relies on the configuration of other clusters, users can directly share the configuration of other cluster services.
Procedure
1. Log in to the YI-MapReduce management console.
2. Click on My Cluster and choose a running cluster to enter the cluster information page.
3. Click the YI-MapReduce Manager tab, and then select Go to YI-MapReduce Manager.
4. Upon entering the YI-MapReduce Manager, click Cluster Service on the menu to go to the cluster service list.
5. Choose the specific cluster service. Click on the cluster service name to enter the cluster service details page.

10. Click Save to complete the configuration addition.
Method 4: Copy Configuration from Other Groups
Scenario
If the desired configuration is already present in another group, there is no need to create a new one. Instead, it can be directly copied from the other group to the current group.
Procedure
1. Log in to the YI-MapReduce management console.
2. Click on My Cluster and choose a running cluster to enter the cluster information page.
3. Click the YI-MapReduce Manager tab, and then select Go to YI-MapReduce Manager.
4. Upon entering the YI-MapReduce Manager, click Cluster Service on the menu to go to the cluster service list.
5. Choose the specific cluster service. Click on the cluster service name to enter the cluster service details page.
6. Click the Configuration Management tab.
7. Choose the configuration group for adding new configurations. Hover over the configuration group name, and click on the Add Configuration icon on the right. The right side of the page will show the new configurations.

9. Select the configuration group and configuration to copy.
10. Click Save to complete the configuration addition.
Cautions
Modifying the copied configuration file, or altering the original configuration from which it was copied, does not impact either configuration.
