Reviewers: JIRA
Implement join for aliases from storage handler which supports indexed access
Some storage like hbase supports indexed access on particular columns. But
hive does not exploits that kind of traits currently.
Further, i heard that some companies already implemented secondary indexing
on hbase. It will be a great to provide pluggable interfaces for them.
