Yes you can.
If the job you are iterating is the same, then just put the job
submission in a loop. For example :
for(int i=0;i<something;i++) {
if(isDone())
break;
JobConf job = new JobConf(conf);
job.addInputPath("foo");
job.setOutputPath("bar");
//set job parameters accordingly
JobClient.runJob(job);
}

Hello:
According the Map/Reduce working flow, it runs map first, then reduce.
Could I run this pairs for several iterations(i.e. to run map/reduce several
times
and stop for certain criteria, like some iterative methods in
numerical-analysis)?
If the answer is yes, any example to do that?
