Error message

list databases failed

What it means

DorisCatalog.listDatabases wraps SQLException from the all-databases query into CatalogException('list databases failed'); metadata listing could not be completed, usually due to connection or permission problems rather than an empty cluster.

Solutions

1. Verify the JDBC connection is alive and the FE is healthy
2. Grant the configured user privileges to see databases
3. Retry after transient network failures
