Subject [jira] [Commented] (ATLAS-271) Hive data model import fails if there exists any type of name "hive_process"
Date Mon, 02 Nov 2015 09:05:27 GMT

Shwetha G S commented on ATLAS-271:
-----------------------------------

The way to address it is by using namespaces for types. It can't be fixed without namespaces

> Hive data model import fails if there exists a type of name "hive_process"
> 1. Create a trait with typename as hive_process. 
> 	For example:
> {noformat}
> curl 'http://localhost:21000/api/atlas/types' -H 'Origin: http://localhost:21000'  -H
'Content-Type: application/json;charset=UTF-8' --data-binary '{"enumTypes":[],"traitTypes":[{"superTypes":[],"typeName":"hive_process","attributeDefinitions":[],"hierarchicalMetaTypeName":"org.apache.atlas.typesystem.types.TraitType"}],"structTypes":[],"classTypes":[]}'
--compressed
> {noformat}
> 2. Now run import_hive.sh
> Import hive data model fails because atlas thinks that hive data model is already registered.
> This issue is quite possible when the user/admin(mostly unaware of hive data model and
its types) is creating tags while bringing atlas.
> hive data model is just an example, this issue can happen with any data model.
> One solution might be to restrict creating types with reserved keywords.
