Subject [jira] [Commented] (YARN-6623) Add support to turn off launching privileged containers in the container-executor
Date Thu, 21 Sep 2017 20:14:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16175386#comment-16175386
] 

Junping Du commented on YARN-6623:
----------------------------------

bq. We have already documented that the docker feature is alpha, not for production use (and
documenting more). Given this, I don't think we should add more risk to 2.8.2.
That's also my initial thinking, but [~shanekumpf@gmail.com] convinced me offline that this
is important for 2.8.2 even as an alpha feature - indeed still alpha for 2.9 and 3.0 and seems
to affect non-docker container runtime. So I change my mind to support this backport. [~vvasudev],
[~shanekumpf@gmail.com] and [~miklos.szegedi@cloudera.com], what do you guys think?

> Currently, launching privileged containers is controlled by the NM. We should add a flag
to the container-executor.cfg allowing admins to disable launching privileged containers at
the container-executor level.
