Subject [jira] [Commented] (PHOENIX-2743) HivePhoenixHandler for big-big join with predicate push down

bq    . I would assume that it's not necessary for any of them, but let me know if I'm wrong

Actually I added that only for the packages that are not in the dependencies in the root pom.xml.
Not sure whether it's good to include them there since they are used in this package only
and the module has it's own artifact. If we want to make it as a part of phoenix-client.jar,
those dependencies can be moved to the root pom.xml and specify the version there.

Ah! I'm with you now. Convention states that we should have all dependencies declared in dependencyManagement
and just refer to dependencies by groupId:artifactId in sub-modules. I will clean that up
too (super easy to change). Thanks.

> 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.

> please, review my proposal.
