Subject [jira] [Commented] (HIVE-2599) Support Composit/Compound Keys with HBaseStorageHandler
Date Mon, 06 Jan 2014 17:20:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13863122#comment-13863122

Nick Dimiduk commented on HIVE-2599:
------------------------------------

After a cursory review, patch v3 looks good to me also. It should be trivial to extend these
concepts to provide a LazyStructObjectInspector over the Strict/StructIterator types in HBase.
Let me see about finding time to do so this week.

> It would be really nice for hive to be able to understand composite keys from an underlying
HBase schema. Currently we have to store key fields twice to be able to both key and make
data available. I noticed John Sichi mentioned in HIVE-1228 that this would be a separate
issue but I cant find any follow up. How feasible is this in the HBaseStorageHandler?
