title: How to specifically determine input for each map step in MRJob?
body: <p>I am working on a map-reduce job, consisting multiple steps. Using mrjob every step receives previous step output. The problem is I don't want it to.</p>
  
  <p>What I want is to extract some information and use it in second step against all input and so on. Is it possible to do this using mrjob?</p>
  
  <p><strong>Note</strong>: Since I don't want to use emr, <a href="https://stackoverflow.com/questions/9302580/multiple-inputs-with-mrjob">this question</a> is not much of help to me.</p>
  
  <p><strong>UPDATE</strong>: If it would not be possible to do this on a single job, I need to do it in two separate jobs. In this case, is there any way to wrap these two jobs and manage intermediate outpus, etc?</p>
