Unable to create a collection on Solr cloud
<p>I am unable to create a collection named 'testCollection' in the Solr Cloud.</p>

<p><strong>URL:</strong> :8080/solr/admin/collections?action=CREATE&amp;name=testCollection</p>

<p><strong>Response:</strong> :</p>

<pre><code>&lt;str name="Operation create caused exception:"&gt;
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: No config set found to associate with the collection.
&lt;/str&gt;
</code></pre>

<p><strong>As per the documentation:</strong> (<a href="https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI" rel="nofollow">https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI</a>) for create collction API, <code>"collection.configName"</code> is not a mandatory field.  If not provided, Solr will default to the collection name as the configuration name.</p>

<p>Why am I still facing this issue?</p>

<p>Is collection.configName mandatory? </p>

<p>How do I find out the associated collection.configName on zookeeper?</p>
