Subject [jira] [Commented] (PHOENIX-2743) HivePhoenixHandler for big-big join with predicate push down
Date Mon, 11 Apr 2016 21:34:25 GMT


ASF GitHub Bot commented on PHOENIX-2743:

Github user ss77892 commented on the pull request:
    Actually I want to get some integration tests in the similar way as it was done in PHOENIX-331,
but there is a clash between versions. This implementation uses Hive 1.2.1, so to run Hive
minicluster it's require hadoop version >=  2.6, but hbase artifacts are still using 2.5,
so it's hard to get all those miniclusters run together. I still hope to get it resolved.
That's why the pom contains dependencies on calcite, hbase-test and others. 
    I will add javadocs and clean commented code where it's possible.

> 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
> 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.
> please, review my proposal.
