             Summary: Add support for HDFS heterogeneous storage testing to TestDFSIO
                 Key: MAPREDUCE-6578
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6578
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
            Reporter: Wei Zhou
            Assignee: Wei Zhou


HDFS heterogeneous storage allows user to store data blocks to different storage medias according to predefined storage policies. Only 'Default' policy is supported in current TestDFSIO implementation. This is going to add an new option to enable tests of other storage polices.
