title: Confirming compression is enabled for specific Hive tables
body: <p>I need to benchmark a series of tables, some compressed and some not. I compress by setting:</p>
  
  <pre><code>hive&gt; SET hive.exec.compress.output=true;
  hive&gt; SET mapred.output.compression.codec=org.apache.hadoop.io.compress.SnappyCodec;
  </code></pre>
  
  <p>...and using INSERT OVERWRITE to populate a table. Is there a way to confirm via the command line (similar to DESCRIBE EXTENDED) that output compression is enabled for a particular table?</p>
