             Summary: Allow users to be able to specify an implementation of IMetaStoreClient
via HiveConf
                 Key: HIVE-12679
                 URL: https://issues.apache.org/jira/browse/HIVE-12679
             Project: Hive
          Issue Type: Improvement
          Components: Configuration, Metastore, Query Planning
            Reporter: Austin Lee
            Assignee: Austin Lee
            Priority: Minor


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
