Sriharsha Chintalapani commented on HIVE-18799:
-----------------------------------------------

[~alangates] SchemaVersion contains actual schema text(avro) and some meta info 
related to that. SchemaBranch, on the other hand, holds branch name, 
description etc. We have a mapping table which contains the relationship 
between a schema branch and schema version. This is to determine for a given 
schema version which branch it exists in.
