> Hi,
> I would like to propose a change that would make it possible for users to
> choose an implementation of IMetaStoreClient via HiveConf, i.e.
> hive-site.xml. Currently, in Hive the choice is hard coded to be
> SessionHiveMetaStoreClient in org.apache.hadoop.hive.ql.metadata.Hive. There
> is no other direct reference to SessionHiveMetaStoreClient other than the
> hard coded class name in Hive.java and the QL component operates only on the
> IMetaStoreClient interface so the change would be minimal and it would be
> quite similar to how an implementation of RawStore is specified and loaded in
> hive-metastore. One use case this change would serve would be one where a
> user wishes to use an implementation of this interface without the dependency
> on the Thrift server.
>
> Thank you,
> Austin
