> Since user normally uses Alluxio as a read cache, I think we can firstly
verify carbon on alluxio for the query scenario. As I am still not very sure
what is the correct way to implement rename for Alluxio, in the meantime, we
can merge this PR first. So please rebase it. @chandrasaripaka
@jackylk My first try wants to use alluxio for query only as you said. But
hive stores table location and carbon blocks `alter location` command, I have
to create table after carbon runs on alluxio. Please mind this problem.
