Description

1. Created a tag tag1.
2. Created a table table1.
3. tag1 is not associated to table1
The following query returns 500 Internal server error.

/api/atlas/v2/entity/guid/<guid of table1>/classification/tag1

Exception thrown :
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
Attached the complete exception trace thrown in application logs.

4. Now created another tag tag2 and associated table1 to tag2.
5. Now the same query /api/atlas/v2/entity/guid/<guid of table1>/tag1 returns expected error code 404.

That is , when any tag is already associated to the entity, search for the unassociated tag throws 404 , else 500.
