-----------------------------------------

             Summary: LocatedFileStatusFetcher to collect/publish IOStatistics
                 Key: MAPREDUCE-7315
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7315
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: client
    Affects Versions: 3.3.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran



Part of HADOOP-16830: if a FileSystem's RemoteIterators implement IOStatisticsSource, then collect these and serve through the IOStatisticsSource API.

If the iterators don't (only S3A does, but ABFS will too), then nothing is collected
