             Summary: MR FileInput/Output formats to aggregate IOStatistics
                 Key: HADOOP-17274
                 URL: https://issues.apache.org/jira/browse/HADOOP-17274
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs
    Affects Versions: 3.3.1
            Reporter: Steve Loughran


The MR input formats are where IO takes place, so collect stats. Justifiable if 
Hive/Spark use these (I think they do).
