I'm trying to connect to solrCloud using solrj CloudSolrClient, but am getting errors.
Used to directly call a single solr node, now switching to solrcloud. I have tried various different url formats as specified from documentation online.
SolrClient solrClient = new CloudSolrClient.Builder(zkUrl).build();
SolrQuery solrQuery = new SolrQuery();
solrQuery.setRequestHandler(FIELD_LIST_HANDLER);
QueryRequest req = new QueryRequest(solrQuery);
req.setBasicAuthCredentials(zkUser, zkPassword);
QueryResponse response = req.process(solrClient, core);
When using the following zkHost strings I get the various errors.

What do I need to change to successfully query solr through zookeeper using solrj CloudSolrClient?
I have successfully communicated with the zookeeper instance from terminal.
$ echo stat | nc host 2181

It turns out that both solrurls and zkurls can be provided to the CloudSolrClient.Builder. I was able to get past the previous issue by using the SolrClient solrClient = new CloudSolrClient.Builder(hosts, Optional.empty()).build();which accepts zkUrls whereas CloudSolrClient.Builder(hosts).build() accepts solr Urls
