Subject [jira] [Created] (YARN-7693) ContainersMonitor support configurable
Date Tue, 02 Jan 2018 02:55:01 GMT
Jiandan Yang  created YARN-7693:
-----------------------------------

             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.
