title: How to share custom filters in solr cluster setup?
body: <p>I have written a custom Solr filter and in a single node setup, I have placed the lib in ${solr_instance}/lib folder and it works fine. </p>
  
  <p>I wanted to use the same custom filter in cluster environment.</p>
  
  <p>I know that the config files are uploaded to zookeeper  and all the nodes download the config folder from zookeeper. </p>
  
  <p>But how does the custom filters work? Will the jars get uploaded to zookeeper same like config files or I need to place the jars in each node.</p>
  
  <p>If it gets uploaded to zookeeper, how should I do the configuration?</p>
  
  <p>I am trying out in Solr 4.4.0 version and the clustering is managed by Cloudera manager 4.7.0.</p>
