How to concatenate the elements of int array to string in Hive
<p>I'm trying to concatenate the element of int array to one string in <a href="/questions/tagged/hive" class="post-tag" title="show questions tagged &#39;hive&#39;" rel="tag">hive</a>.</p>

<p>The function <code>concat_ws</code> works only for string arrays, so I tried <code>cast(my_int_array as string)</code> but it's not working.</p>

<p>Any suggestion?</p>
