>                 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
>            Priority: Major
>
> 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.
