[jira] [Commented] (YARN-2718) Create a CompositeConatainerExecutor that combines DockerContainerExecutor and DefaultContainerExecutor

    [ https://issues.apache.org/jira/browse/YARN-2718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14292258#comment-14292258 ] 

Chris Douglas commented on YARN-2718:
-------------------------------------

I share Allen's skepticism. Adding this to the CLC is an invasive change. If the purpose is debugging, wouldn't a composite CE that does the demux be sufficient? Are there other use cases this supports?

> There should be a composite container that allows users to run their jobs in DockerContainerExecutor, but switch to DefaultContainerExecutor for debugging purposes.
