Big SQL is integrated with YARN through Apache Slider since Big SQL 4.2.5 (improvements have been made in Big SQL 5.0.1 in this area). When a component requests resources from YARN, it is put on a YARN priority queue and YARN schedules the allocation based on priority. When the request ... Read More
