> Error after updating attribute's data type of an Atlas type
> ------------------------------------------------------------
>
> Key: ATLAS-1730
> URL: https://issues.apache.org/jira/browse/ATLAS-1730
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 0.8-incubating
> Reporter: Sharmadha Sainath
> Assignee: Apoorv Naik
> Fix For: 0.9-incubating, 0.8.1-incubating
>
>
> 1.Created a type with one of its attributes' type as date and POSTed the type
> definition to
> {code}
> /api/atlas/v2/types/typedefs
> {code}
> 2. Tried to update the attribute data type to string , hence modified the
> JSON (changed "date" to "string") and PUT the JSON to the same API which
> succeeded.
> 3. Tried to create an entity of the type and provided "val1" as value for the
> string attribute (which was updated from date).
> 4. Entity creation failed with
> {code}
> java.lang.ClassCastException: java.lang.Long cannot be cast to
> java.lang.String
> {code}
> This could be a rare one but this scenario might cause issues when user
> initially gave data type as "date" by mistake and wants to update it as
> "string".
> Also , since attribute delete is not allowed as part of type update ,
> attribute with "date" type can't be deleted and recreated with string.
