Ich habe eine lokale zwei Instanzen Solr Cloud-Setup mit einer einzigen zoekeeper-Instanz. Ich versuche, mich über SolrJ zu verbinden, um eine Abfrage auszuführen, jedoch hängt mein Code für etwa 2 Minuten beim Ausführen der Abfrage und schlägt dann fehl. Ich habe das grundlegende Beispiel auf dem Solr-Wiki verfolgt. Die logs/Code untenSolrJ hängen bei der Verbindung zu zookee

und mein Code:
String zkHostString = "localhost:2181";
CloudSolrClient solr = new CloudSolrClient.Builder().withZkHost(zkHostString).build();
solr.setDefaultCollection("foo");
SolrQuery query = new SolrQuery();
query.set("q", "*:*");
QueryResponse response = null;
try {
response = solr.query(query);
} catch (SolrServerException e) {
return null;
}
//Do Something with the results...
