Hi, In implementing the ThriftHiveMetastore.Iface we have run into some issues understanding the get_foreign_keys(ForeignKeysRequest<https://hive.apache.org/javadocs/r2.1.1/api/org/apache/hadoop/hive/metastore/api/ForeignKeysRequest.html> request) method contract. We are receiving ForeignKeysRequest’s from hive cli( query: ‘describe formatted db1.table1’). The table has a FK constraint on another table. The ForeignKeysRequest.getParent_db_name() returns null. The documentation is sparse on what the `parent_db_name` and `foreign_db_name` represent, and after a number of educated guesses we felt it would be best to consult the mailing list. If possible could someone please explain these fields?
Thanks, Courtney Edwards, Software Engineer Hotels.com – an Expedia Group Brand
