Subject [jira] [Commented] (YARN-5771) Provide option to send env to be whitelisted in ContainerLaunchContext
Date Thu, 27 Oct 2016 16:24:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15612405#comment-15612405

Daniel Templeton commented on YARN-5771:
----------------------------------------

Sorry for restating the obvious.  I missed the context of MAPREDUCE-6704.

I don't think that letting users control the whitelisting on a per-job basis is the right
answer.  As far as I can tell, the problem we're trying to solve here is that it should just
work out of the box.  The simplest and sanest answer, IMO, is what you proposed on MAPREDUCE-6704:
add {{HADOOP_MAPRED_HOME}} to {{yarn.nodemanager.env-whitelist}} by default.  I agree with
[~aw] that users aren't going to be offended by a little pollution if it means things just
work.

> As per current implementation ENV to be white listed for container launch is are configured
as part of {{yarn.nodemanager.env-whitelist}}
> Specific to container we cannot specify additional ENV properties to be whitelisted.
As part of this jira we are providing an option to provide additional whitelist ENV.
