Subject Re: [jira] [Created] (YARN-443) allow OS scheduling priority of NM to be different then the containers it launches
Date Sat, 02 Mar 2013 17:31:51 GMT
Just a thought,
This is can be achieved with the help of scripts in unix/linux but I guess we need to have
jni calls for windows api to achieve the same.

Thomas Graves created YARN-443:
----------------------------------

             Summary: allow OS scheduling priority of NM to be different then the containers
it launches
                 Key: YARN-443
                 URL: https://issues.apache.org/jira/browse/YARN-443
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 0.23.6, 2.0.3-alpha
            Reporter: Thomas Graves
            Assignee: Thomas Graves


It would be nice if we could have the nodemanager run at a different OS scheduling priority
then 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.
