Hello. Hive would create a new Tez AM to coordinate the query (or use an existing one if HS2 session pool is used). However, the YARN app for Tez should only have a single container. Is this not the case? If it’s running additional containers, what is hive.llap.execution.mode set to? It should be set to all or only by default (“all” means run everything in LLAP if at all possible; “only” is the same with fallback to containers disabled - so the query would fail if it cannot run in LLAP).

Thanks Rajesh
