--------------------------------------------
Hi [~ngangam] Sorry for not getting back earlier. In my opinion schema version
of the db is a implementation detail which end users should not be exposed to.
So having the source code (project version) exposed it more reasonable since it
can be tied with the APIs easily in the future.
> Metastore API getVersion() should return real version

> Currently I see the {{getVersion}} implementation in the metastore is
> returning a hard-coded "3.0". It would be good to return the real version of
> the metastore server using {{HiveversionInfo}} so that clients can take
> certain actions based on metastore server versions.
> Possible use-cases are:
> 1. Client A can make use of new features introduced in given Metastore
> version else stick to the base functionality.
> 2. This version number can be used to do a version handshake between client
> and server in the future to improve our cross-version compatibity story.
