Hadop after using partitioner, the result is still a file, how to solve??

Recently looked at the partitioner, so according to write a case, finally found that the program did not write the results separately to the corresponding file, the result is a file, so it is not a cluster to run the program, found control or local code execution:

As a result, think of packaging to the cluster to run to see, the results of the node reported a variety of errors! ：

Finally, the problem is still unresolved, which hero pointed it. Little brother's not getting started! In this heavens!!!
