Thomas Graves commented on YARN-443: ------------------------------------ after thinking about it some more the issue with using nice means the NM needs to have sudo access on linux to do negatives values (more favorable priorities) and I was hoping to leave that open as an option. I'll go investigate other possibilities. > allow OS scheduling priority of NM to be different than 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: 2.0.3-alpha, 0.23.6 > Reporter: Thomas Graves > Assignee: Thomas Graves > Attachments: YARN-443.patch, YARN-443.patch > > > 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. -- This message is automatically generated by JIRA.
