Ways to serialize and clone a job in MapReduce

[xeonmailinglist]

Hi,

1.

   I am trying to find ways to serialize and clone a job in MapReduce.
   Is it possible?

2.

   Is there a way to convert |org.apache.hadoop.mapreduce.Job| into a
   xml or json file, and then the opposite?

3. If I use Oozie I can clone a job, by duplicating the job definition
   in the xml file?

Thanks
