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.
