Abin Shahab commented on YARN-2477:
-----------------------------------

[~drankye], I am eluding to the fact that Kerberized Yarn Cluster currently 
requires LinuxContainerExecutor.
See these instructions:

> DockerContainerExecutor must support secure mode

> DockerContainerExecutor(patch in YARN-1964) does not support Kerberized 
> hadoop clusters yet, as Kerberized hadoop cluster has a strict dependency on 
> the LinuxContainerExecutor. 
> For Docker containers to be used in production environment, they must support 
> secure hadoop. Issues regarding Java's AES encryption library in a 
> containerized environment also need to be worked out.
