             Summary: Enable non-staged mapjoin [Spark Branch]
                 Key: HIVE-8912
                 URL: https://issues.apache.org/jira/browse/HIVE-8912
             Project: Hive
          Issue Type: Sub-task
            Reporter: Szehon Ho


HIVE-6144 enabled non-staged mapjoin where data is read directly from 
small-table instead of dumping to a hashfile and reading it from there.  It is 
disabled on MapReduce due to some concerns of perf and security.

This JIRA is to evaluate enabling this optimization on Spark.
