Sergey Shelukhin commented on HIVE-10744:
-----------------------------------------
Update on another run with 500 maps it got stuck on the 3rd DAG so I guess it's
not based on the number of tasks...
> LLAP: dags get stuck in yet another way

> DAG gets stuck when number of tasks that is multiple of number of containers
> on machine (6, 12, ... in my case) fails to finish at the end of the stage (I
> am running a job with 500-1000 maps). Happened twice on 3rd DAG with 1000-map
> job (TPCH Q1), then when I reduced to 500 happened on 7th DAG so far.
> [~sseth] has the details.
