I have couple of questions about execution engine coming with Hive 2.1
I recently downloaded MapR 5.2 sandbox and playing around with it.
For hive 2.1, i see mapreduce is deprecated and recommending to use tez or spark as an execution engine.
is mapreduce still the default execution engine in hive 2.1 ?
do you guys support spark as an execution engine in hive 2.1?
or do you guys encourage using Spark sql integrated with hive ?
