Currently we are using Spark Sql with Hive thrift server and Es-hadoop connector. Spark version : 1.4.1. Es-hadoop connector : 2.2.0. Elasticsearch 1.4.4.
If we have relationships in the Elasticsearch data model via parent-child relationship or nested objects, does the Es-hadoop connector push appropriate queries down to Elasticsearch? I mean does it convert the sql join statements to nested query or has_child or has_parent query?
