Spark SQL thriftserver DDL?

Elastic Stack Elasticsearch
2

I've figured out the corresponding Spark SQL syntax. The following temporary table works:

CREATE TEMPORARY TABLE biblio_raw (
   url   STRING,
  content_text_array ARRAY<STRING>
)
USING org.elasticsearch.spark.sql 
OPTIONS (
  path 'my_index/doc', 
  query '?q=mouse',
  es.port '11100',
  es.mapping.names 'content_text_array:contentText'
);

HOWEVER, the es.mapping.names do NOT work. The above DDL does not map content_text_array SQL field to the contentText ES field. How do I express mappings with Elasticsearch/Spark SQL?
