Summary: [YARN-8851] Phase 1 - Support device isolation in native container-executor
Key: YARN-9060
URL: https://issues.apache.org/jira/browse/YARN-9060
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Zhankun Tang
Assignee: Zhankun Tang
Due to the cgroups v1 implementation policy in linux kernel, we cannot update the value of the device cgroups controller unless we have the root permission ([here|https://github.com/torvalds/linux/blob/6f0d349d922ba44e4348a17a78ea51b7135965b1/security/device_cgroup.c#L604]). So we need to support this in container-executor for Java layer to invoke.
