Subject [jira] [Commented] (HIVE-6411) Support more generic way of using composite key for HBaseHandler
Date Mon, 24 Mar 2014 16:12:43 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13945282#comment-13945282
] 

Xuefu Zhang commented on HIVE-6411:
-----------------------------------

Because of HIVE-6677, this patch needs some rework anyway, I'd think we it might be better
we just get it done in one chunk. It seems Navis isn't available for this, but if anyone would
like to take this forward, please communicate and feel free to do so.

> 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}
