             Summary: Use thread pool to improve the speed of creating control files in TestDFSIO
                 Key: MAPREDUCE-7462
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7462
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: examples, test
    Affects Versions: 3.3.6
            Reporter: farmmamba


When we use TestDFSIO tool to test the throughouts of HDFS clusters, we found it is so slow in the creating controll files stage. 

After refering to the source code, we found that method createControlFile try to create control files serially. It can be improved by using thread pool.
