morningman opened a new pull request, #22001: URL: https://github.com/apache/doris/pull/22001
## Proposed changes When init an external catalog/database, non-master FE will forward the init request to master FE, master FE will to the init operation(connecting to external data source, etc.). If there are some error happen in init operation, master FE will return error message to non master FE. But previously, the error message is unclear such as `Interna error processing initExtemnalCtlMeta`, we have to see the fe.log of master FE to see the root cause. This PR, I return the root cause to non-master FE directly, to make debug easier: ``` mysql> show databases; -------------- show databases -------------- ERROR 1105 (HY000): RuntimeException, msg: org.apache.doris.common.UserException: errCode = 2, detailMessage = MetaException(message:Could not connect to meta store using any of the URIs provided. Most recent failure: shade.doris.hive.org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused (Connection refused) ``` ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
