Hi Hyunsik, The iceberg-hive module is used to track Iceberg tables in a Hive metastore. Right now, there is no support in Hive for reading Iceberg tables.
I don't know of any efforts to add Iceberg table support to Hive. I've heard that it wouldn't be too difficult, but it would require implementing a new RawStore and also some way to decide which RawStore to use when loading a table because iceberg-hive uses the same namespace as regular Hive tables in the Hive Metastore. Are you interested in contributing support to Hive? rb On Wed, May 22, 2019 at 10:30 PM Hyunsik Choi <hyun...@apache.org> wrote: > Hi folks, > > I have couple of questions about iceberg-hive module.
