    Description

      Currently the read test in TestDFSIO benchmark just opens a large side file and measures the read performance. The MR scheduler has no opportunity to do any optimization for the TestDFSIO MR application. The side-effect of this is that it is very hard to do any meaningful analysis of the results of the benchmark i.e. to check if node-local or rack-local or off-switch read performance improved/degraded.
