> DockerContainerExecutor must support secure mode
> ------------------------------------------------
>
> Key: YARN-2477
> URL: https://issues.apache.org/jira/browse/YARN-2477
> Project: Hadoop YARN
> Issue Type: New Feature
> Reporter: Abin Shahab
> Priority: Major
> Labels: security
>
> 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.
