---------------------------------
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
