How do i customize the name of the job?

When a Job is submitted it is given an ID say job_200904211745_0018 in Hadoop.

But for some reason i want to submit it with ID say "job1". How can i do that ?

From the documentation at http://hadoop.apache.org/common/docs/r0.20.2/api/org/apache/hadoop/mapreduce/JobID.html it says

Applications should never construct ... JobID strings, but rather use appropriate constructors or forName(String) method.

How exactly the forName function operates, not sure; haven't used it myself.

If you want to construct a 'Name' for specific jobs, there is the JobName, which can be set by the job's setJobName. This is what I use to identify what the job is when I review the M/R Admin page.

Your actual reasons, instead of "for some reason", may help the hive-mind to come up with other options, or maybe someone faced the same reasoning and has a solution they can share.

The more background and information about the issue you are encountering that you share tends to allows more detailed responses with more applicable solutions.
