Alan Gates commented on HCATALOG-419:
-------------------------------------
Also, when discussing this we agreed that it would be checked into a special
directory for language specific clients. That way if others add similar
bindings for other languages we can accomodate them as well. This will also
keep the interface out of the main HCat jar. We can generate other language
specific packages for each of these client implementations.

> Key: HCATALOG-419
> URL: https://issues.apache.org/jira/browse/HCATALOG-419
> Project: HCatalog
> Issue Type: New Feature
> Affects Versions: 0.4.1

> There are presently three ways to issue HCatalog DDL commands:
> Command line interface
> REST APIs (upcoming)
> HiveMetaStore Client
> Presently, java developers go through the Hive meta store (HMS) client
> interface to issue HCatalog DDl commands. Though the HMS client interface is
> public, it is not intended for public users. According to the hive user
> mailing list, the HMS client is not a public API and is subject to change in
> the future. So, it will be a good idea to have a java APIs in HCatalog which
> will provide a protect users from the changes made to the hive meta store
> client. Also, the under the covers either the Rest APIS or the hive metastore
> client can be used to provide end users with the required data.
