Sergey Shelukhin updated HIVE-10744:
------------------------------------
Description: 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). Status just hangs forever
(beyond 5 min timeout) with some tasks shown as running. 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. (was: DAG gets stuck when number of tasks
