Vineet Garg commented on HIVE-19323:
------------------------------------

bq. We could also just not create 4 scripts on master until we actually have a 
4 release
What if there is a change in master which make changes in metastore but is not 
targeted for 3.x release (i.e. targeted only for 4.0 release). We will need 
upgrade scripts from 3.x to 4.0 in this case.
IMO we should add scripts for both 3.0 to 3.1 and then 3.1 to 4.0. We will keep 
renaming 3.1 to 4.0 scripts with every 3.x release. This will preserve the 
meta-store changes intended for 4.x only.

> Create metastore SQL install and upgrade scripts for 3.1
