我有一个本地的两个实例Solr Cloud设置了一个zookeeper实例。我试图通过SolrJ进行连接来执行查询,但是我的代码在执行查询时挂起了2分钟左右,然后失败。我遵循Solr wiki上的基本示例。日志/代码如下SolrJ在连接到zookeeper时挂起

,我的代码是:
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...
