How can I configure Analytics Engine use Hive LLAP using the Ambari UI?

Question

Is Hive LLAP feature supported by IAE? If yes, how to enable it using the Ambari UI?

I tried to enable based on a tutorial from Hortonworks but I am getting errors:

$ hive

I have followed the procedure described in https://hortonworks.com/tutorial/interactive-sql-on-hadoop-with-hive-llap/, and it works.

I think, something that you should pay attention is about change the YARN memory as recommended, and one thing that is not in the procedure is to enable the "Pre-emption" YARN feature.
