getting error: "No collection param specified on request and no default collection has been set."

[hectoralicea]

I'm trying to use a zookeeper Solr Cloud destination for my norconex Committer

<solrClientType>CloudSolrClient</solrClientType>

and cannot understand how I tell the com.norconex.committer.solr.SolrCommitter XML fragment which collection to commit to when the <solrURL> that's provided is simply a comma delimited list of hosts with no URL there for no collection name attached to the URL.

 *   <dt>CloudSolrClient</dt>
 *     <dd>For use with a SolrCloud cluster. Needs a comma-separated list
 *         of Zookeeper hosts.</dd>

as shown here in the comments

committer-solr/src/main/java/com/norconex/committer/solr/SolrCommitter.java

Line 80 in ac03a9d

* <dt>CloudSolrClient</dt>

The error I'm getting is

my xml fragment for SolrCommitter is

      <!-- Decide what to do with your files by specifying a Committer. -->
