Hello there,
I'm interested in understanding the Hive Metastore catalog support. I see
references in the metastore code to catalogs, for example:
https://github.com/apache/hive/blob/17525f169b9a08cd715bfb42899e45b7c689c77a/standalone-metastore/metastore-common/src/main/protobuf/org/apache/hadoop/hive/metastore/hive_metastore.proto#L45
But I don't see create/drop catalog statements in the HiveQL DDL, neither in
the documentation nor in the code:
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL
https://github.com/apache/hive/tree/17525f169b9a08cd715bfb42899e45b7c689c77a/ql/src/java/org/apache/hadoop/hive/ql/ddl
Could anyone clarify the state of support for catalogs in the metastore? Are
there known applications leveraging this catalog support?
Thanks,
-Flavio
