Subject [jira] [Commented] (YARN-443) allow OS scheduling priority of NM to be different than the containers it launches
Date Wed, 06 Mar 2013 15:48:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13594794#comment-13594794
] 

Thomas Graves commented on YARN-443:
------------------------------------

Can you elaborate on your proposal.  Are you saying use a yarn config and then pass an argument
into the container executor or do something actually higher up like call nice when calling
the container-executor?   What do you propose for the DefaultContainerExecutor since it could
run across multiple platforms and all it does is call a bash script?

I figured with it in the container-executor itself each one could more easily decide if it
applies and how exactly to implement it. I also like the fact that I can change it without
rebooting the NM.

> It would be nice if we could have the nodemanager run at a different OS scheduling priority
than the containers so that you can still communicate with the nodemanager if the containers
out of control.  
> On linux we could launch the nodemanager at a higher priority, but then all the containers
it launches would also be at that higher priority, so we need a way for the container executor
to launch them at a lower priority.
> I'm not sure how this applies to windows if at all.
