<@U06TM7M40RK> message desc org.apache.ranger.plugin.model.RangerserviceDef Data not found

23

The error message “org.apache.ranger.plugin.model.RangerserviceDef Data not found” typically indicates that the service definition you are trying to register or access in Apache Ranger is not found or not correctly set up. Here are some steps you can take to troubleshoot and resolve this issue:

  1. Verify Service Definition: Ensure that the service definition JSON file (servicedef.json) is correctly formatted and contains all the necessary fields. You can use a JSON validator to check the syntax.

  2. Check Ranger Logs: Review the Apache Ranger logs for any additional error messages or warnings that might provide more context about the issue. The logs are typically located in the Ranger installation directory under ews/logs.

  3. Ensure Correct API Endpoint: Make sure you are using the correct API endpoint for registering the service definition. The endpoint should be /service/public/v2/api/servicedef.

  4. Validate Ranger Configuration: Double-check the configuration of your Apache Ranger instance to ensure it is set up to accept service definitions. This includes verifying any security settings or access controls.

  5. Test with a Simple JSON: Try using a very simple JSON payload to see if the issue is with the JSON content. This can help isolate whether the problem is with the JSON structure or the server configuration.

  6. Network Connectivity: Ensure there are no network issues preventing the curl command from reaching the Ranger server. You can test connectivity by pinging the Ranger host or using a tool like telnet to check the port.

  7. Use Verbose Output: Use the -v flag with your curl command to get verbose output. This will provide more detailed information about the request and response, which can help identify where the issue might be occurring.

    curl -v -u <ranger-admin-username>:<ranger-admin-password> -X POST -H "Accept: application/json" -H "Content-Type: application/json" --data @servicedef.json http://<ranger-host>:6080/service/public/v2/api/servicedef

If these steps do not resolve the issue, please let me know, and I can provide more detailed troubleshooting steps.

<@U06TM7M40RK> Can u provide a valid
servicedef.json for ranger datahub

25

To create a valid servicedef.json for integrating Apache Ranger with DataHub, you need to ensure that the JSON file is correctly formatted and includes all necessary fields for defining a service in Ranger. Unfortunately, the exact content of the servicedef.json is not provided in the data sources. However, I can guide you on how to structure it based on typical requirements for a service definition in Apache Ranger.

Here’s a general outline of what the servicedef.json might include:

  1. Service Name: A unique name for the service.
  2. Description: A brief description of the service.
  3. Resources: Define the resources that the service will manage, such as datasets, dashboards, etc.
  4. Access Types: Specify the types of access that can be granted, such as read, write, delete, etc.
  5. Policy Conditions: Define any conditions that apply to the policies.
  6. Configurations: Include any specific configurations required for the service.

Here is a simplified example of what the servicedef.json might look like:

{
  "name": "ranger_datahub",
  "description": "Service definition for DataHub integration with Apache Ranger",
  "resources": [
    {
      "name": "dataset",
      "type": "string",
      "mandatory": true,
      "lookupSupported": true
    }
  ],
  "accessTypes": [
    {
      "name": "read",
      "label": "Read"
    },
    {
      "name": "write",
      "label": "Write"
    }
  ],
  "policyConditions": [],
  "configs": []
}

Please note that this is a basic example and may need to be adjusted based on your specific requirements and the version of Apache Ranger you are using. You should refer to the Apache Ranger documentation for more detailed information on creating service definitions.

If you have access to the DataHub or Ranger community, you might also find more specific examples or templates shared by other users.

Would you like more detailed guidance on any specific part of the service definition?
