Jitendra Nath Pandey commented on HIVE-4850:
--------------------------------------------

I think you need to set following configurations to force a map join:


set hive.auto.convert.join=true;
set hive.auto.convert.join.noconditionaltask=true;
set hive.auto.convert.join.noconditionaltask.size=1000000000;

> Implement vectorized JOIN operators
