Hi Simon,
Thanks for reporting the problem. There is some rough edges around catalog
API and table environments, and we are improving post 1.9 release.
Nevertheless, tableEnv.registerCatalog() is just to put a new catalog in
Flink's CatalogManager, It doens't change the default catalog/database as
you expected. To switch to your newly registered catalog, you could call
tableEnv.useCatalog() and .useDatabase().
As an alternative, you could fully qualify your table name with a
"catalog.db.table" syntax without switching current catalog/database.
Please try those and let me know if you find new problems.
Thanks,
Xuefu
