Subject Does HCatalog subsume Metastore?
Date Wed, 04 Feb 2015 10:14:15 GMT
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
