    Description

      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.
