Description

I started a local SolrCloud instance with two nodes and two replicas per node.  I created one empty collection on each node.  So I guess I have two shard per collection.
 
I tried to use the ping method in Solrj to verify my connected client.  When I try to use it, it throws ...
 
Caused by: org.apache.solr.common.SolrException: No collection param specified on request and no default collection has been set: []
at org.apache.solr.client.solrj.impl.BaseCloudSolrClient.sendRequest(BaseCloudSolrClient.java:1071) ~[solr-solrj-8.2.0.jar:8.2.0 31d7ec7bbfdcd2c4cc61d9d35e962165410b65fe - ivera - 2019-07-19 15:11:07]
 
I cannot pass a collection name to the ping request.  And the CloudSolrClient.Builder does not allow me to declare a default collection.  BaseCloudSolrClient.setDefaultCollection(String) is effectively deprecated because CloudSolrClient no longer has a public constructor. 
 
Can we add an argument to the Builder constructor to accept a string for the default collection?  Or a new setter on the Builder?
