title: Has anyone use mapred.job.tracker=local in hadoop streaming job?
body: <p>in last weeks, we use hadoop streaming to calculate some reports everyday. Recently we made a change to our program, if the input size is smaller than 10MB, we will set mapred.job.tracker=local in the JobConf, then the job will run locally.</p>
  
  <p>But last night, many jobs failed, with status 3 returned by runningJob.getJobState().
  I don't know why, and there is nothing in the stderr.</p>
  
  <p>I can google nothing related about this question. So I'm wondering if I should use mapred.job.tracker=local in production mode? Maybe it's just a debug solution in developing supplied by hadoop.</p>
  
  <p>Has anyone know something about it? Anything, Any infomation, Thank you.   </p>
