Wei Yan updated YARN-2194: -------------------------- Attachment: YARN-2194-1.patch A prelim patch that implements the systemd-based cpu resource isolation for Redhat 7. A summary: (1) Create a new resource handler SystemdLCEResourceHandler. Users can use this handle by configuring the field "yarn.nodemanager.linux-container-executor.resources-handler.class". (2) For each container, create one slice and one scope. The scope is put inside the slice, and cpuShare isolation is also attached to the slice. All container's slices are organized in a root slice (named "hadoop_yarn.slice" in default). Will add some testcases later. > Add Cgroup support for RedHat 7 > ------------------------------- > > Key: YARN-2194 > URL: https://issues.apache.org/jira/browse/YARN-2194 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Wei Yan > Assignee: Wei Yan > Attachments: YARN-2194-1.patch > > > In previous versions of RedHat, we can build custom cgroup hierarchies with > use of the cgconfig command from the libcgroup package. From RedHat 7, > package libcgroup is deprecated and it is not recommended to use it since it > can easily create conflicts with the default cgroup hierarchy. The systemd is > provided and recommended for cgroup management. We need to add support for > this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
