> {{DFSTestUtils.copyFile()}} is implemented by copying data through
> FileInputStream / FileOutputStream. Apache Common IO provides
> {{FileUtils.copyFile()}}. It uses FileChannel which is more efficient.
> This jira proposes to implement {{DFSTestUtils.copyFile()}} using
> {{FileUtils.copyFile()}}.
