Subject [jira] [Commented] (HIVE-6411) Support more generic way of using composite key for HBaseHandler
Date Thu, 17 Jul 2014 18:25:08 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14065302#comment-14065302

Gautam Kowshik commented on HIVE-6411:
--------------------------------------

Have we tried to back port this to Hive .13 .. This is a very useful feature to have for hive
over hbase in the current stable version as well. If not i can try looking into this in a
separate jira.

> HIVE-2599 introduced using custom object for the row key. But it forces key objects to
extend HBaseCompositeKey, which is again extension of LazyStruct. If user provides proper
Object and OI, we can replace internal key and keyOI with those. 
> Initial implementation is based on factory interface.
> {code}
> public interface HBaseKeyFactory {
>   void init(SerDeParameters parameters, Properties properties) throws SerDeException;
>   ObjectInspector createObjectInspector(TypeInfo type) throws SerDeException;
>   LazyObjectBase createObject(ObjectInspector inspector) throws SerDeException;
> }
> {code}
