> NullPointerException - The issue was because both hive_table and
> hive_storagedesc define columns(list<hive_column>) as composite attribute and
> the same hive_column entity is shared between both. Same entity can't be
> composite entity of multiple entities, doesn't make sense from the definition
> of composition. Two fixes are required here -
> 1. create entity should fail if a composite entity is shared - ATLAS-459
> 2. Fix hive integration to not use the same hive_column entity across
> hive_table and hive_storagedesc. should be fixed in this jira
