[jira] [Created] (YARN-8184) Too many metrics if containerLocalizer uses ReadWriteDiskValidator

Yufei Gu created YARN-8184:
------------------------------

             Summary: Too many metrics if containerLocalizer uses ReadWriteDiskValidator
                 Key: YARN-8184
                 URL: https://issues.apache.org/jira/browse/YARN-8184
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Yufei Gu


ContainerLocalizer will use the ReadWriteDiskValidator as its disk validator when it downloads files if we configure the yarn.nodemanger.disk-validator to ReadWriteDiskValidator's name. In that case, ReadWriteDiskValidator will create a metric item for each directory localized, which will be too many metrics. We should let ContainerLocalizer only use the basic disk validator.
