> We need to set this to 'tez' to reflect that we have deprecated 'mr':
> https://github.com/apache/hive/blob/bd16e0098916aa5fc2dede99492c6a240b51e677/common/src/java/org/apache/hadoop/hive/conf/HiveConf.java#L4567
> I'm expecting lots of UT failures because of this, as we're still running
> those on mr (which might be fine where the actual unit test is not closely
> related to the execution engine), so we'll see what to do.
