Facing the same issue.
HMS version: 2.3.6
https://github.com/apache/amoro/blob/master/amoro-core/src/main/java/org/apache/amoro/formats/iceberg/IcebergCatalog.java#L56

This functions is giving out empty namespaces. Thus, list_databases and list_tables is giving empty results.

The metastore does contain a lot of tables. However, I don't see any errors in the logs.

@palash-goel Can you build the binary release using mvn clean package -DskipTests -Phadoop2 and try to deploy the AMS again?
