DataHub

Hi How should I fill in this `access token`when I initialize it

`datahub init`
`/root/.datahubenv already exists. Overwrite? [y/N]: y`
`Configure which datahub instance to connect to`
`Enter your DataHub host [<http://localhost:8080>]:` 
`Enter your DataHub access token (Supports env vars via `{VAR_NAME}` syntax) []:` 

<@U02C9L8F0HG> for the oss datahub, you can just hit enter to skip entering an access token. The access token feature in the datahub cli is used for authentication when sending metadata to the cloud-hosted version of DataHub.

`datahub delete --urn "DEV"`
 When I execute this command to remove the URN, it will report an error like this:
`Received error, please check your ~/.datahubenv`

`{'exceptionClass': 'com.linkedin.restli.server.RestLiServiceException', 'stackTrace': "com.linkedin.restli.server.RestLiServiceException ...........java.lang.reflect.Method.invoke(Method.java:498)\n\tat com.linkedin.restli.internal.server.RestLiMethodInvoker.doInvoke(RestLiMethodInvoker.java:172)\n\t... 75 more\n", 'message': 'INTERNAL SERVER ERROR', 'status': 500}`

I didn't think anything else in the env file would affect my ability to delete it, so I thought I'd need to set the appropriate token

Hmm do other Datahub commands like `ingest list-runs` work?

the urn you are deleting seems like a strange urn though. Usually urns will look like `urn:li:dataset:…`

Maybe use a valid urn and see if you are able to delete the metadata?

I'm not sure what you mean. I'm specifying the URN when I specify env in the YML file
My YML file looks like this:
`source:`
  `type: mysql`
  `config:`
    `# Coordinates`
    `host_port: url:3306`
    `database: arc`
    `env: DEV`


    `# Credentials`
    `username: username`
    `password: password`

`sink:`
  `# sink configs`
  `type: "datahub-rest"`
  `config:`
    `server: "<http://127.0.0.1:8080>"`

e.g. the URN for this dataset (<https://demo.datahubproject.io/dataset/urn:li:dataset:(urn:li:dataPlatform:snowflake,demo_pipeline.public.all_entities,PROD)/Schema?is_lineage_mode=false|https://demo.datahubproject.io/dataset/urn:li:dataset:(urn:li:dataPlatform:snowflake,dem[…]ne.public.all_entities,PROD)/Schema?is_lineage_mode=false>)

is: `urn:li:dataset:(urn:li:dataPlatform:snowflake,demo_pipeline.public.all_entities,PROD)`

hopefully this helps you identify the urn in your setup

Thank you very much! I just successfully removed a URN from the example you gave
But the one I want to remove is DEV
I tried to use "`datahub delete --urn "urn:li:dataset:(urn:li:dataPlatform:DEV)`"" to delete it, but it didn't work
`Successfully deleted urn:li:dataset:(urn:li:dataPlatform:DEV). 0 rows deleted`

Hi <@U02C9L8F0HG> DEV isn’t really a data platform, it is an environment. Are you trying to delete all things that in the “DEV” environment?

there isn't a single command to do this... you would have to find all the entities in the DEV environment and delete them one by one
