Subject [jira] [Commented] (YARN-443) allow OS scheduling priority of NM to be different than the containers it launches
Date Fri, 08 Mar 2013 14:18:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13597154#comment-13597154
] 

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

I intended to leave that log message in there because if anything comes back on stderr from
try running the container, it goes into the exception but then its never logged. I'll actually
go ahead and remove that and file a follow up jira as ideally any message would go into the
diagnostics that get returned to the user also.  

I'll fix the typo for than and commit.

> 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.
