我正在尝试使用Solr 6.2.0和Zookeeper 3.4.8创建一个使用Vagrant框的SolrCloud设置
我设法让它与Solr 6.1.0完美配合，但我无法启动 使用Solr 6.2.0在云模式下的一个节点。
我有四个虚拟机连接在Vagrant盒子的专用网络上，一个运行Zookeeper，和 三个Solr节点。
第一个Solr节点按预期连接到Zookeeper。我可以访问管理员并查看 云信息。
但是当我尝试连接第二个节点时，出现了问题。
我在Solr日志中收到以下错误：

它确实从最后开始，但它无法正常工作，我只是在Solr管理员中遇到错误。
我可以找到错误的唯一参考：
“之前的短暂活动节点仍然存在.Solr无法继续。请确保没有 使用相同端口的其他Solr进程已经运行。“
，是这张Jira票，但它表明该问题已在6.2.0中解决
https://issues.apache.org/jira/browse/SOLR-8777
还有其他人遇到过此问题吗？有关解决的任何提示吗？
编辑：在尝试连接第二个节点之前，绝对没有与Solr的连接。每个节点都在一个完全独立的VM上，因此端口不会发生冲突（无论如何都会导致不同的故障）。我甚至用pgrep -f solr来仔细检查。什么都没有。
