Repeated export and import of hive meta store metadata throws artifacts already exists error

Open WAG10 opened this issue 2 years ago • 0 comments

Hi Team, We are facing issue as artifacts already exists error on hive meta store metadata export/import

Steps to replicate:

  • Create some internal managed tabled in primary workspace

  • Export the metastore tables using below command: python3 migration_pipeline.py --export-pipeline --profile oldWS --azure --keep-tasks metastore

  • Once exported, import the same using below command:
    python3 migration_pipeline.py --import-pipeline --profile newWS --azure --keep-tasks metastore --session

  • This will import the hms metadata, Now repeat the same process again

  • this time we get error during import as tables already exists. 2023-10-03,07:24:01;INFO;Importing table default.employee 2023-10-03,07:24:04;ERROR;AnalysisException: Table default.employee already exists 2023-10-03,07:24:04;INFO;Importing table default.orders_features 2023-10-03,07:24:04;ERROR;AnalysisException: Table default.orders_features already exists

  • Same happens for even update too when we update the already exported table in primary and export it again, Expectation is that it should always import it even if we have the table in secondary so that updates can be posted to the hms metadata
