Aaron Dossett commented on ATLAS-409:
-------------------------------------
[~shwethags] This is an interesting scenario. With the schema defined in a
file, it's possible the schema in the file can change in allowed ways. This
can definitely happen with avro, which allows schema changes. If the bridge
does read the columns through the schema file, how would atlas keep up to date
if the schema file changes?
> Atlas will not import avro tables with schema read from a file

>
> Atlas won't import a Hive table with no columns (see below for an example of
> a valid hive table with no explicit columns). This is because the Atlas Hive
> Storage Descriptor class REQUIRES columns, but the Hive Table class allows
> them to be OPTIONAL.

> ROW FORMAT SERDE
