-----------------------------------

             Summary: Configure Tez cartesian product edge based on LLAP cluster size
                 Key: HIVE-16690
                 URL: https://issues.apache.org/jira/browse/HIVE-16690
             Project: Hive
          Issue Type: Bug
            Reporter: Zhiyuan Yang
            Assignee: Zhiyuan Yang


In HIVE-14731 we are using default value for target parallelism of fair cartesian product
edge. Ideally this should be set according to cluster size. In case of LLAP it's pretty easy
to get cluster size, i.e., number of executors.
