Subject [jira] [Commented] (PHOENIX-2743) HivePhoenixHandler for big-big join with predicate push down
Date Tue, 19 Apr 2016 21:07:25 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15248640#comment-15248640
] 

Josh Elser commented on PHOENIX-2743:
-------------------------------------

bq. Could it be that you have core-site.xml in your path/classpath and it interfere with the
test? 

I unset all of my {{HADOOP_*}} environment variables and that did the trick. It seems like
I should be filing a bug against MiniMR now (goody).

I'll see if I can come around with a quick workaround (or at least warning for others who
might run into it) and then push these changes.

Thanks for your help, Sergey!

> 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.
