Does CloudSolrServer hit zookeeper for every request?

[Jonnakuti, Vijayalatha]

Hi
We have too many zookeeper connections and had to increase max client 
connection on zookeeper(3.4.6)

The underlaying problem looks like,
CloudSolrServer makes a connect call to zookeeper for every request  but never 
disconnects.
 Am I supposed to call getZkStateReader().close() for every request? Or am I 
missing something?

Solr Configuration is

<autoCommit>
  <maxDocs>10000</maxDocs>
  <maxTime>900000</maxTime>
  <openSearcher>false</openSearcher>
</autoCommit>
<commitWithin>
  <softCommit>true</softCommit>
</commitWithin>
<autoSoftCommit>
       <maxTime>10000</maxTime>
</autoSoftCommit>

Thanks.,
Vijaya
