Subject [jira] [Commented] (PHOENIX-2743) HivePhoenixHandler for big-big join with predicate push down
Date Fri, 11 Mar 2016 02:47:40 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15190388#comment-15190388

JeongMin Ju commented on PHOENIX-2743:
--------------------------------------

Oh, you right. my mistake.
LazyObjectInspectorParameters, LazySerDeParameters classes were created from Hive 1.2.
For now, it is supported above Hive 1.2.
To enable from a previous version additional work is required, if necessary.

> Phoenix support hash join & sort-merge join. But in case of big*big join does not
process well.
> Therefore Need other method like Hive.
> I implemented hive-phoenix-handler that can access Apache Phoenix table on HBase using
HiveQL.
> hive-phoenix-handler is very faster than hive-hbase-handler because of applying predicate
push down.
> I am publishing source code to github for contribution and maybe will be completed by
next week.
> https://github.com/mini666/hive-phoenix-handler
> please, review my proposal.
