> * look for new AM pid
> Here, 2nd AM container was suppose to be started on
> container_e12_1450825622869_0001_02_000001. But AM was not launched on
> container_e12_1450825622869_0001_02_000001. It was in AQUIRED state.
> On other hand, container_e12_1450825622869_0001_02_000002 got the AM running.
> Expected behavior: RM should not start 2 containers for starting AM
