### Description of PR 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. After optimizing, the TestDFSIO tool runs quicker than before. ### How was this patch tested? In our product cluster. -- This is an automated message from the Apache Git Service.
