[MAPREDUCE-6271] org.apache.hadoop.mapreduce.Cluster GetJob() display warn log

• Type: Bug

Description

When using getJob() with MapReduce 2.7, warn log caused by configuration loaded twice is displayed every time. And when job completed, this function will display warn log of "java.io.FileNotFoundException"

And I think this is related with MAPREDUCE-5875, the change in GetJob() seems to be not needed, cause it's only for test.
