-------------------------------
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.
