title: Best place for json Serde JAR in CDH Hadoop for use with Hive/Hue/MapReduce
body: <p>I'm using <strong>Hive/Hue/MapReduce with a json Serde</strong>. To get this working I have copied the <strong>json_serde.jar</strong> to several lib directories on every cluster node:</p>
  
  <ul>
  <li>/opt/cloudera/parcels/CDH/lib/hive/lib</li>
  <li>/opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/lib</li>
  <li>/opt/cloudera/parcels/CDH/lib/hadoop/lib</li>
  <li>/opt/cloudera/parcels/CDH/lib/hadoop-0.20-mapreduce/lib</li>
  <li>...</li>
  </ul>
  
  <p>On every CDH update of the cluster I have to do that again.
  Is there a more elegant way where the <strong>distribution of the Serde in the cluster</strong> would be automatic and <strong>resistant to updates</strong>?</p>
