Description
k-NN introduced validation to prevent index creation api to accept method paramters that are used by approximate k-NN search algorithm. For ex: create index api accepts model_id, or, method params even if knn index setting was not true before 2.17.
However, for index that were created before 2.17 and upgraded to 2.17, will prevent cluster to parse those previously accepted index mapping.
Hence, k-NN will allow those paramters for indices that were created before 2.17, but doesn't support those parameters starting 2.17.
