[jira] [Created] (YARN-6729) NM percentage-physical-cpu-limit should be always 100 if DefaultLCEResourcesHandler is used

Yufei Gu created YARN-6729:
------------------------------

             Summary: NM percentage-physical-cpu-limit should be always 100 if DefaultLCEResourcesHandler is used
                 Key: YARN-6729
                 URL: https://issues.apache.org/jira/browse/YARN-6729
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.0.0-alpha3
            Reporter: Yufei Gu


NM percentage-physical-cpu-limit is not honored in DefaultLCEResourcesHandler, which may cause container cpu usage calculation issue. e.g. container vcore usage is potentially more than 100% if percentage-physical-cpu-limit is set to a value less than 100.
