Alan Gates commented on HIVE-17751:
-----------------------------------

Can I propose a slightly different approach here?  Rather than try to move this 
in one or even a few big patches, can we agree first on the submodules and then 
you can have a series of patches where you move code a bit at a time so that 
you don't keep getting stomped on by others making changes?  It looks like 
you're trying to separate it into three modules:

standalone-metastore/metastore-common

standalone-metastore/metastore-client

standalone-metastore/metastore-server

Is that right?  I'm fine with that, though since client has only 3 files in it 
and it will pull in common it might make sense to combine those.  

Then your next patch can move just 50 or 100 of the 300+ files you're trying to 
move into common, and go from there.

> external applications which are interfacing with HMS should ideally only 
> include HMSClient library instead of one big library containing server as 
> well. We should ideally have a thin client library so that cross version 
> support for external applications is easier. We should sub-divide the 
> standalone module into possibly 3 modules (one for common classes, one for 
> client classes and one for server) or 2 sub-modules (one for client and one 
> for server) so that we can generate separate jars for HMS client and server.
