[jira] [Created] (HADOOP-10271) Use FileUtils.copyFile() to implement DFSTestUtils.copyFile()

Haohui Mai created HADOOP-10271:
-----------------------------------

             Summary: Use FileUtils.copyFile() to implement DFSTestUtils.copyFile()
                 Key: HADOOP-10271
                 URL: https://issues.apache.org/jira/browse/HADOOP-10271
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai
            Priority: Minor
         Attachments: HDFS-5825.000.patch

{{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()}}.
