Subject Re: Hive query starts own session for LLAP
Date Mon, 25 Sep 2017 15:33:23 GMT
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).

Subject:  Hive query starts own session for LLAP

HI All,
When I execute the hive query , that  starts its own session and creates
new yarn jobs rather than using the llap enabled job
Can you please provide some suggestion?
