-----------------------------------
Summary: ContainersMonitor support configurable
Key: YARN-7693
URL: https://issues.apache.org/jira/browse/YARN-7693
Project: Hadoop YARN
Issue Type: New Feature
Components: nodemanager
Reporter: Jiandan Yang
Assignee: Jiandan Yang
Priority: Minor
Currently ContainersMonitor has only one default implementation
ContainersMonitorImpl,
After introducing Opportunistic Container, ContainersMonitor needs to monitor
system metrics and even dynamically adjust Opportunistic and Guaranteed
resources in the cgroup, so another ContainersMonitor may need to be
implemented. The current ContainerManagerImpl ContainersMonitorImpl direct new
ContainerManagerImpl, so ContainersMonitor need to be configurable.
