    Description

      Data transfer was tested with simulated exceptions as below:

      1. create files with dfs
      2. write 1 byte
      3. close file
      4. open the same file
      5. read the 1 byte and compare results

      The file was closed successfully but we got an IOException(Could not get block locations...) when the file was reopened for reading.
