I think the issue was by ths following , Somehow I forgot about global ordinals. They are the reason why I'm still getting fielddata usage even after using doc_values as global ordinals cannot be included in doc_values.

it fixes the issue After your cluster upgrade to 2.1.2, you should perform an index upgrade of your old indices so that they get migrated to the new Lucene format.
All the new indices you will create in 2.1.2 will have doc values enabled by default, so there's nothing special to be done there.
