title: Concatenate Two Tables in Pig
body: <p><strong>EDIT</strong> Evidently I did not read the Pig docs closely. The <code>UNION</code> operator is what I'm looking for (e.g. <code>C = UNION A, B;</code>).</p>
  
  <p>Assume I have two tables in Pig, <code>A</code> and <code>B</code> that look as follows:</p>
  
  <pre><code>A=
  (1)
  (2)
  (3)
  
  B=
  (4)
  </code></pre>
  
  <p>How do I generate and third table, <code>C</code> that concatenates tables <code>A</code> and <code>B</code>:</p>
  
  <pre><code>C=
  (1)
  (2)
  (3)
  (4)
  </code></pre>
