title: Running multiple mapreduce jobs with oozie?
body: <p>As part of a workaround, I wanted to use two mapreduce jobs(instead of one) that ought to run in sequence for giving the desired affect.</p>
  
  <p>The map function in each job simply emit each key,value pair without processing. The reduce functions in each job are different as they do different kind of processing.</p>
  
  <p>I stumbled upon oozie and it seem to directly writes to the input stream of the consequent job (or doesn't it?) - this would be great since the intermediate data is large (I/O operation would become a bottleneck).</p>
  
  <p>How can I achieve this with oozie (2 mr jobs in the workflow)? </p>
  
  <p>I did go through the below resources, but they simply run a single job as a workflow:

  <p>Help appreciated.</p>
  
  <p>Cheers</p>
