Question

我有一个本地两个实例Solr Cloud设置，只有一个zookeeper实例。我试图通过SolrJ连接执行查询但是我的代码在执行查询时会挂起2分钟左右然后失败。我已经按照Solr wiki上的基本示例进行了操作。日志/代码在

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...

Urgh，我是一个白痴，zookeeper实例和solr实例都在docker里面，上面发布的代码不是。所以Zookeeper使用docker containers ip报告了solr url ...主机需要通过localhost而不是docker容器ip连接。

例如：Zookeeper回复[http://172.17.0.5:8983/solr/foo_shard1_replica2，http://172.17.0.6:8984/solr/foo_shard1_replica1] 但我的代码需要调用[http://localhost:8983/solr/foo_shard1_replica2，http://localhost:8984/solr/foo_shard1_replica1]

我认为我也有类似的问题。我在端口8983 + 9983上的远程计算机（solr-1）上运行了Solr + Zookeeper-在内部，它们是具有172.22.X.X地址的docker-compose网络（可在该计算机上本地访问，但不能在我的代码运行的位置）。但是，端口8983和9983已暴露，并且访问Solr Admin UI（在solr-1：8983上运行）可以正常工作。

当我尝试使用SolrJ进行连接时，我正在使用CloudSolrClient-初始化如下：

 new CloudSolrClient.Builder(zkHosts, Optional.empty()).build()

其中zkHosts仅包含' solr-1：9983 “（转义）。我发送请求后，他立即调用getLiveNodes并返回本地地址（172.22.XX）而不是全局主机名（solr-1：9983）。因为我显然无法访问该主机名，所以我超时了。

听起来像您的问题吗？你有什么想法？您认为问题是SolrJ还是我设置Solr / Zookeeper + Docker的方式？

这是我的docker-compose文件的样子：

version: '2'
services:
    solr:
        image: solr
        container_name: solr    
        ports:
            - "9983:9983"
            - "8983:8983"
        networks:
            - solr 
        entrypoint:
            - docker-entrypoint.sh
            - solr
            - start
            - -c
            - -f
networks:
    solr:

连接到zookeeper时SolrJ挂起
