Removing Owners From Datasets

Why Would You Remove Owners?​

Assigning an owner to an entity helps to establish accountability for the metadata and collaborating as a team. If there are any issues or questions about the data, the designated owner can serve as a reliable point of contact.

Goal Of This Guide​

This guide will show you how to remove the owner John Doe from the SampleHdfsDataset datatset.

Pre-requisites​

For this tutorial, you need to deploy DataHub Quickstart and ingest sample data. For detailed information, please refer to Datahub Quickstart Guide.

note

Before removing owners, you need to ensure the targeted dataset and the owner are already present in your datahub. If you attempt to manipulate entities that do not exist, your operation will fail. In this guide, we will be using data from a sample ingestion.

Remove Owners With GraphQL​

note

Please note that there are two available endpoints (:8000, :9002) to access graphql. For more information about the differences between these endpoints, please refer to DataHub Metadata Service

GraphQL Explorer​

GraphQL Explorer is the fastest way to experiment with GraphQL without any dependencies. Navigate to GraphQL Explorer (http://localhost:9002/api/graphiql) and run the following query.

mutation removeOwners {
    removeOwner(
      input: {
        ownerUrn: "urn:li:corpuser:jdoe",
        resourceUrn: "urn:li:dataset:(urn:li:dataPlatform:hdfs,SampleHdfsDataset,PROD)",
            }
    )
}

Note that you can also remove owners from multiple entities or subresource using batchRemoveOwners.

mutation batchRemoveOwners {
    batchRemoveOwners(
      input: {
        ownerUrns: ["urn:li:corpuser:jdoe"],
        resources: [
          { resourceUrn:"urn:li:dataset:(urn:li:dataPlatform:hdfs,SampleHdfsDataset,PROD)"} ,
          { resourceUrn:"urn:li:dataset:(urn:li:dataPlatform:hive,fct_users_created,PROD)"} ,]
      }
    )
}

Expected Response:

{
  "data": {
    "removeOwner": true
  },
  "extensions": {}
}

CURL​

With CURL, you need to provide tokens. To generate a token, please refer to Access Token Management. With accessToken, you can run the following command.

curl --location --request POST 'http://localhost:8080/api/graphql' \
--header 'Authorization: Bearer <my-access-token>' \
--header 'Content-Type: application/json' \
--data-raw '{ "query": "mutation removeOwner { removeOwner(input: { ownerUrn: \"urn:li:corpuser:jdoe\", resourceUrn: \"urn:li:dataset:(urn:li:dataPlatform:hdfs,SampleHdfsDataset,PROD)\" }) }", "variables":{}}'

Remove Ownerships With Python SDK​

Following codes remove an owner named John Doe from a dataset named SampleHdfsDataset.

Coming Soon!

We're using the MetdataChangeProposalWrapper to change entities in this example. For more information about the MetadataChangeProposal, please refer to MetadataChangeProposal & MetadataChangeLog Events

Expected Response:

{ "data": { "removeOwner": true }, "extensions": {} }

Expected Outcomes​

You can now see John Doe has been removed as an owner from the fct_users_created dataset.
