[jira] [Commented] (YARN-1964) Create Docker analog of the
LinuxContainerExecutor in YARN
[ https://issues.apache.org/jira/browse/YARN-1964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14241589#comment-14241589 ]
Chen He commented on YARN-1964:
-------------------------------
Thank [~ashahab] for the patch. It will be more clear if we add "only support single node cluster" in the [working example]. Since the "fs.defaultFS" is configured to be "hdfs://localhost:9000" in sequenceiq/hadoop-docker:2.6.0. If we use it in a distributed environment, the MRAppMaster will not find hdfs and fail.

> Docker (https://www.docker.io/) is, increasingly, a very popular container technology.
> In context of YARN, the support for Docker will provide a very elegant solution to allow applications to *package* their software into a Docker container (entire Linux file system incl. custom versions of perl, python etc.) and use it as a blueprint to launch all their YARN containers with requisite software environment. This provides both consistency (all YARN containers will have the same software environment) and isolation (no interference with whatever is installed on the physical machine).
