Shwetha G S commented on ATLAS-409:
-----------------------------------
With the integration of falcon and sqoop, the columns field in hive_table
should be optional. One instance is, for sqoop hive import, sqoop hook creates
hive_table entity with the minimum set of attributes(just table name and db
reference). When the hive table is accessed later through hive, other
attributes of the hive_table are updated. So, lets keep the columns as optional
attribute in hive_table.
Good to know that columns are populated even in case of external serde. Thanks
for investigating

> 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.
