Description

Hi, guys~

I wish to discuss about HCatalogStore.

HiveMetaStore types consists of three types: embedded, local, remote.
This type will set up at hive configuration file which named 'hive-site.xml' and HiveMetaStoreClient can use MetaStore by configuration file. So, if Tajo have only to add hive configuration file to classpath, Tajo can use HiveMetaStore with HiveMetaStoreClient.

But current HCatalogStore set up configurations about HiveMetaStore as follows:

• hive.metastore.uris
• hive.metastore.kerberos.principal
• hive.metastore.local
• hive.metastore.sasl.enabled

And Tajo doesn't need 'tajo.catalog.uri' property because 'hive-site.xml' already includes metastore host and port. So, it looks like unnecessary settings.

What do you think about this suggestion?
