> 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.
