Subject [jira] [Commented] (YARN-2477) DockerContainerExecutor must support secure mode
Date Sat, 30 Aug 2014 17:58:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-2477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14116501#comment-14116501

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

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

> 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.
