    Description

      MapReduce Job, the task initialization by job.xml , but if missing the soft link of "job.xml" file,will do nothing under the quietmode of Configuration.
      Such as map tasks as directly output to HDFS without reduce tasks of job, if map task missing job.xml, it's will run with default behavior, just as IdentityMapper and output to local, and resulting in data loss.
