HCatalog supports all types of Hive tables. You can think of it as basically and access layer for non-Hive clients to read and write Hive's metadata.

Hi everybody, I want to add support for reading Hive-managed data to Apache Flink and have a question regarding the overlap of HCatalog and Hive metastore. Is it sufficient to add support for HCatalog or do we also need to add an InputFormat for "regular" Hive metastore tables? So basically, does the HCatalogInputFormat only provide access to tables which were created and managed through HCatalog or can it also read "regular" Hive tables in setups that do not use HCatalog? Thanks and best regards, Fabian
