Subject [jira] [Commented] (HIVE-2599) Support Composit/Compound Keys with HBaseStorageHandler
Date Mon, 06 Jan 2014 14:25:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13863009#comment-13863009

Brock Noland commented on HIVE-2599:
------------------------------------

Great to hear, it sounds like the composite key is working as desired -- both inserts and
selects work as expected!

The patch looks good to me as well!  The only change required I noticed is that the two new
classes related to the composite keys require apache license headers. I can commit this after
that change!

> 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?
