Troubleshooting "Unable to emit metadata to DataHub GMS" Error

Original Slack Thread

datahub.configuration.common.OperationalError: (‘Unable to emit metadata to DataHub GMS’, {‘message’: “HTTPConnectionPool(host=‘datahub-gms’, port=8080): Max retries exceeded with url: /aspects?action=ingestProposal (Caused by NewConnectionError(‘<urllib3.connection.HTTPConnection object at 0x7f8c921a2850>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution’))”})

Please tell me how to fix this error. I just don’t know.

GMS host is not reachable for your ingest job for some reason
you may check
• are you using the correct GMS URL name in ingest recipe
• gms is up and running
• connectivity between where you running ingest and gms
