[jira] [Created] (HDFS-15335) Report top N metrics for files in get listing ops

Chao Sun created HDFS-15335:
-------------------------------

             Summary: Report top N metrics for files in get listing ops
                 Key: HDFS-15335
                 URL: https://issues.apache.org/jira/browse/HDFS-15335
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs, metrics
            Reporter: Chao Sun


Currently HDFS has {{filesInGetListingOps}} metrics which tells the total number of files in all listing ops. However, it will be useful to report the top N users who contribute most to this. This can help to identify the potential bad users and stop the abusing against NameNode.
