Hi Thomas Cozien,
Not sure which Hive and tez version you are working with. Please note according to https://maprdocs.mapr.com/52/Hive/HiveandTez-Troubleshooting.html , HiveServer2 on Tez doesn't concurrent queries within one session.
Thanks Cathy for your answer,
I'm using MapR 5.2 and so the same versions as mentioned within the issue. I've already find the Hive one but maybe someone found a workaround. Maybe have you some recommendations on the way to use Tez with Yarn queues (for 200 people) ?
I have not used Tez with Yarn before. However, find following resource for you to check out:
Hope it is helpful.
