> The re-partitioning the data is a very expensive operation. By the way, 
> currently, we processes read/write operations sequentially using HDFS api in 
> BSPJobClient from client-side. This causes potential too many open files 
> error, contains HDFS overheads, and shows slow performance.
> We have to find another way to re-partitioning data.
