title: How to get all table definitions in a database in Hive?
body: <p>I am looking to get all table definitions in Hive.  I know that for single table definition I can use something like -</p>
  
  <pre><code>  describe &lt;&lt;table_name&gt;&gt;
    describe extended &lt;&lt;table_name&gt;&gt;
  </code></pre>
  
  <p>But, I couldn't find a way to get all table definitions. Is there any table in megastore similar to Information_Schema in mysql or is there command to get all table definitions ?</p>
