Hitesh Shah commented on TEZ-3128:
----------------------------------

bq.  Could you help me to clarify where to fix? 

The ContainerLauncher I think seems to be the one as per my understanding. Lets wait for [~sseth]
or [~rajesh.balamohan] to supply additional logs to pinpoint the problem.

> During an AM shutdown, the TaskCommunicator is also shutdown and it tries to stop containers
in the shutdown thread itself. This can cause the AM shutdown to block if NMs are not available.
> This likely affects 0.7 as well.
