title: Hadoop: key and value are tab separated in the output file. how to do it semicolon-separated?
body: <p>I think the title is already explaining my question. I would like to change</p>
  
  <pre><code>key (tab space) value
  </code></pre>
  
  <p>into</p>
  
  <pre><code>key;value
  </code></pre>
  
  <p>in all output files the reducers are generating from the output of mappers.</p>
  
  <p>I could not find good documentation on this using google. Can anyone please give a fraction of code on how to achieve this?</p>
