> 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.
